6ch multi-controlled relay board

I built a multi-controlled relay board for my electronics workbench.

It can be controlled by web interface, HTTP GET, websocket, MQTT, UART (4pin JST header on top) and USB/serial. It also send changes to all these connections.

On the web interface you can define 25 groups of on/off states of the relays. Each group can be recalled by any of the interface methods, and you can also set a group to one of the two buttons for quick manual recalls.

The board works on the 24V supply I have all over my workbench, that's what the two 2pin JST headers are for (2nd one for daisychaining). All relay contacts are on the bottom side, there are two male and two female headers for every COM, NC and NO.

I wrote a little piece of code for my Stream Deck, so I can see and switch states of every relay and also recall every group from it.

I ise this thing to control and especially automate workflows on my electronics workbench. It's great for long run test series of things.

Secure Bluetooth LE adoption on rise in automotive applications

EDN Network - Пн, 12/04/2023 - 10:24

With a developed ecosystem, an ultra-low-power consumption profile, and an established presence in mobile phones, it is understandable why Bluetooth Low Energy (Bluetooth LE) technology has emerged as the preferred wireless protocol for new connectivity use cases in automotive applications.

This article examines the drivers behind the rising use of wireless connectivity in automobiles and reviews some current and potential future use cases for Bluetooth LE.

BLE driving factors in vehicles

The automotive industry is undergoing an unprecedented revolution, with a near-simultaneous convergence in the trends toward electrification, autonomous driving, and vehicle-to-everything (V2X) connectivity. Cars are evolving from providing an essential transport service to providing occupants with a rewarding travel experience. Vehicle occupants will increasingly look to use their smartphones to gain access to their vehicles and customize this experience.

In addition, as the number of sensors, safety and infotainment systems in cars grows, so does the requirement to interconnect them to in-vehicle computers. Here, using cables, which add significant weight and volume to a vehicle, poses challenges for manufacturability, cost, and complexity.

Figure 1 Wireless connectivity in vehicles enhances user experience. Source: onsemi

Bluetooth LE is a low-power and cost-effective alternative to traditional interconnectivity solutions based on controller area networks (CAN) and local interconnect networks (LIN). So, several automotive OEMs are trying to leverage a Bluetooth LE infrastructure to replace these technologies in some use cases.

Bluetooth LE has several advantages over other wireless technologies, which makes it the preferred choice for automotive applications, including:

  • Proven communication with smartphones allays concerns about interoperability
  • Standardized specification and certification
  • Robust performance in electrically noisy and harsh environments
  • Availability of AEC-Q100 automotive qualified parts
  • Low-power consumption which is a critical requirement in electric vehicles
  • Availability of low-cost system-on-chip (SoC) components and antennas

Bluetooth LE automotive use cases

Bluetooth technology in automobiles was first used with vehicle access systems, enabling features like the phone-as-a-key feature for passive-entry and passive-start. Future developments around Bluetooth LE in this application will see customized user experiences based on individual digital keys and profiles. For example, a vehicle will be able to automatically identify a profile stored in a driver’s or passenger’s mobile phone and then seamlessly adjust the position of mirrors, seats, and the steering wheel to match individual preferences.

Additionally, it will be possible to create shared keys for other vehicle users, eventually making phone-as-a-key a practical solution for the emerging trend of shared autonomous vehicles. However, this will also require profiles to be protected by the highest security levels to prevent them from being copied by unauthorized third parties who could steal or alter how the vehicle operates.

Here, it’s worth mentioning that low power is crucial in infotainment systems like telematics boxes and head-unit displays. Often, these systems include high-power-consumption connectivity devices like cellular telecommunications modems, Wi-Fi, and other connectivity protocols. These systems have stringent power budgets that must be adhered to so as not to place a drain on a vehicle’s battery when a car is not in use.

Meeting these requirements is driving system developers to look for low-power wireless MCUs that can shut off the higher power consumption components in the vehicle but still wake them up when needed. Bluetooth LE is an excellent option for this purpose, allowing a telematics box or head-unit display to determine if it needs to wake up to handle over-the-air software updates or perform other diagnostic functions, for example.

Apart from vehicle body applications, another emerging trend is to use radios featuring Bluetooth technology in battery-management systems to send periodic temperature and voltage information about battery packs to the main computer. Bluetooth LE can also help OEMs to reduce costs with features like wireless tire pressure monitoring systems (TPMS) that allow drivers to check tire pressure using their phones or even receive notifications when a tire is flat.

Bluetooth LE can also simplify designs for controlling multi-position power seats, mirrors, locks, and sunroofs. Apart from ultra-low-power consumption, a small form factor and the ability to secure data communication within and outside the vehicle are critical requirements when selecting a Bluetooth LE-enabled MCU for use in a car.

Low-power wireless MCUs

Besides connectivity, wireless MCUs also feature embedded security and ultra-low power for automotive applications. The wireless MCU shown below has four low-power modes to reduce power consumption while maintaining system responsiveness. These include sleep, standby, smart sense, and idle. Smart sense mode takes advantage of the low-power capability of sleep mode while allowing some digital and analog peripherals to remain active with minimal processor intervention.

Figure 2 The NCV-RSL15 wireless MCU is designed with a smart sense power mode. Source: onsemi

These features allow wireless MCUs to support applications like vehicle access, tire pressure, and tire monitoring systems for up to 10 years off the power from a single coin cell. Next, OEMs continue to find ways to exploit Bluetooth LE-enabled MCUs in developing lighter, more scalable battery management systems that are easier to manufacture.

Moreover, the wireless MCU shown above is built around an Arm Cortex−M33 processor core with TrustZone Armv8−M security extensions, which form the basis of its security platform. The MCU also incorporates embedded security with an Arm CryptoCell featuring hardware-based root-of-trust secure boot, many user-accessible hardware-accelerated cryptographic algorithms, and firmware-over-the-air (FOTA) capabilities to support future firmware updates and deployment of security patches.

Such security features make Bluetooth LE-enabled MCUs highly suitable for remote access devices.

New Energy Collaborative Aims to Accelerate Creation of Low-Carbon Energy Access in Asia-Pacific for the Semiconductor Climate Consortium

ELE Times - Пн, 12/04/2023 - 06:36

Energy Collaborative to highlight initial sponsors, partners and mission at COP28 2023 United Nations Climate Change Conference

Aiming to reduce global semiconductor ecosystem carbon emissions, SEMI and the Semiconductor Climate Consortium (SCC) have created the Energy Collaborative (EC) to understand and clear roadblocks to the installation of low-carbon energy sources in the Asia-Pacific region. The EC, a collective of industry leaders, will provide a consolidated view of priorities for low-carbon energy in the region.

“Sharing resources to start this foundational semiconductor industry sustainability work now is important to enable wider access to low-carbon energy in the next five to ten years,” stated Young Bae, SCC Governing Council member and sponsor for the SCC Scope 2 Working Group, and Global Business Director, Advanced Cleans Technologies at DuPont. “One of the key action areas the SCC has identified is the lack of low-carbon energy plans and actions in the Asia-Pacific region. The EC will help the SCC by accelerating investments to broaden access.”

The EC sponsoring companies will anchor the collective’s work to engage in roundtables and fact-finding sessions. Initial sponsors include:

  • Applied Materials
  • AMD
  • ASE
  • ASML
  • JSR
  • Lam Research
  • Macquarie Group
  • Samsung Electronics
  • TotalEnergies
  • TSMC

McKinsey & Company is a Knowledge Partner to the initiative, providing fact-based analysis and support.

“The semiconductor value chain and its downstream partners and customers have a pivotal role to play in the acceleration of low-carbon energy installations, due to their scale in high-priority markets and the extent to which they will drive growth in future energy demands,” stated Ajit Manocha, President and CEO of SEMI. “To reach the emissions reductions goals of the sector, a step function change in ambition and action is required. The EC is focused on that goal – increasing the pace and scaling of access to low-carbon energy.”

A recent SCC report found that the semiconductor value chain is a significant consumer of energy in almost all key Asian markets. Additionally, a recent analysis by McKinsey & Company shows that even with major semiconductor companies’ latest commitments, which are more stringent than past measures, the industry is not on track to limit emissions to the extent required under the 2015 Paris Agreement. The analysis finds that both individual and collective actions by semiconductor players can help the entire industry increase its sustainability effort and meet the 1.5°C challenge.

SEMI representatives will host a special session on December 2 in the Green Zone at COP28 in Dubai, United Arab Emirates. For more information, contact Heidi Hoffman of SEMI at hhoffman@semi.org.

SEMI welcomes additional sponsors and partners of the Energy Collaborative. To join the collaborative or learn more, contact scc@semi.org.

About the Semiconductor Climate Consortium
Focused on overcoming emissions challenges facing the semiconductor value chain, the Semiconductor Climate Consortium (SCC) was formed based on the principles of collaboration, ambition and transparency. SCC working groups are working to establish more accurate emissions reporting, measure the value chain’s progress and accelerate the development of sustainability solutions. An outgrowth of the SEMI Sustainability Initiative, the SCC has more than 90 members.

Little lamp I found at goodwill I decided to upgrade with parts I had laying around

Did it in my free time with spare parts lying around and a lot of hot glue to keep stuff together and insulated. Originally ran off 10-12vac with a brake light. Switched it to 10-12vdc and stuffed a 12v cob led into the lamp part, with a small heatsink and fan to keep it cool. Led stays within operating temps and I’m happy with it

RISC-V’s embedded foray with a 32-bit MCU development

EDN Network - Птн, 12/01/2023 - 17:27

One of the largest vendors of embedded processors has independently developed a CPU core for the 32-bit general-purpose RISC-V market; it can be used as the main CPU or on-chip subsystem and can even be embedded in an application-specific standard product (ASSP).

Renesas Electronics, which has designed and tested a 32-bit CPU core based on the open-standard RISC-V instruction set architecture (ISA), is currently sampling devices based on this new core to select customers. It plans to launch its first RISC-V-based MCU and associated development tools in the first quarter of 2024.

It’s important to note that while several MCU suppliers have announced the development of RISC-V products, Renesas is the first company to unveil a 32-bit RISC-V MCU architecture development. Also worth noting is that the Japanese chipmaker’s 32-bit MCU portfolio includes its proprietary RX Family as well as RA Family based on the Arm Cortex-M architecture.

Another important fact in Renesas’s RISC-V foray is that it has already introduced 32-bit ASSP devices for voice control and motor control built on CPU cores developed by Andes Technology. Renesas has also unveiled 64-bit general-purpose microprocessors (MPUs) built on Andes CPU cores.

Renesas claims its RISC-V CPU achieves a 3.27 CoreMark/MHz performance, outperforming similar architectures in performance and code size reduction. It’s a versatile CPU that is suitable for different application contexts. For instance, it can serve as a main application controller, a complementary and secondary core in system-on-chips (SoCs), and in on-chip subsystems and deeply embedded ASSPs.

Giancarlo Parodi, principal product marketing engineer at Renesas, also claims in his blog that CPU’s implementation is very efficient regarding silicon area. Besides smaller cost impact, it helps reduce operating current and leakage current during standby time. Finally, despite targeting small embedded systems, this RISC-V core provides a high level of computational throughput.

Next, in line with RISC-V ISA foreseeing several ‘extensions’ that target specific functionality more efficiently, Renesas has included extensions to improve performance and reduce code size. Additionally, the CPU core has added a stack monitor register to enhance the robustness of the application software. It will help designers detect and prevent stack memory overflows, a common issue spotted through test coverage alone.

Parodi’s blog provides more details about the CPU features and capabilities and how they assist developers in benchmarking an application and verifying its behavior. More details about its performance score will be available on the EEMBC website once the first product is unveiled in early 2024.

The RISC-V processors, known for their flexibility, are gradually making inroads in the embedded systems landscape. In this design journey, the availability of a homegrown CPU from a major MCU supplier lends RISC-V fray significant credibility in offering embedded processing solutions for a broad range of applications.

8-bit MCUs strengthen code protection

EDN Network - Птн, 12/01/2023 - 16:07

Microchip’s PIC18-Q24 MCUs employ a programming and debugging interface disable (PDID) function that enhances chip-level security. When enabled, this enhanced code protection feature disables the programming/debugging interface and blocks unauthorized attempts to read, modify, or erase firmware.

The PIC18-Q24 microcontroller family also provides a multi-voltage I/O (MVIO) interface. MVIO allows the MCU to interface with digital inputs or outputs at different operating voltages. This integrated level shifting not only eliminates the need for external level shifters, but also reduces both design area and BOM costs. MVIO pins support a voltage range of 1.62 V through 5.5 V.

With PDID and MVIO, PIC18-Q24 8-bit MCUs are particularly useful as system management processors, performing monitoring and telemetry for a larger processor. These routine tasks are typically most vulnerable to potential hackers as they attempt to gain access to embedded systems.

Other features of the PIC18-Q24 include a 10-bit ADC with computation capable of 300 ksamples/s and an 8-bit signal routing port to interconnect digital peripherals without using external pins. The PIC18-Q24 devices are available in a variety of packages with pins counts ranging from 28 to 48 pins.

MORNSUN supports the development of the home energy storage industry

ELE Times - Птн, 12/01/2023 - 13:30


This growing concern about the potential scarcity and limited availability of future energy resources from fossil fuels has allowed the new energy industry to attract much attention. Among them, energy storage is a key technology to improve the reliability of power systems and promote the consumption of new energy sources. The development of home energy storage can help household users save on electricity costs and ensure stable electricity consumption.

Home energy storage: service to home users, an important part of the new energy system

Home energy storage is usually installed in combination with home photovoltaic systems to provide electricity to home users, which can be well adapted to decentralized electricity demand and resource distribution. Developing and complementing together with large-scale energy storage systems, home energy storage will become an important part of a new type of power system with renewable energy as the main source, with a wide scope for development and promising prospects.

MORNSUN supports the development of the home energy storage industry-2

As an energy supply device, the endurance of a home energy storage system is paramount. In order to ensure that the system consumes as little power as possible in standby mode, the power supply, which is the core component of the device, is particularly important and must be considered in terms of reliability, efficiency, and low power consumption.

The key advantages of MORNSUN’s power supply for home storage system: low power consumption and ultra-wide input voltage range With a focus on innovation and advanced technology in power supply for energy storage for more than one decade, MORNSUN has been at the forefront of providing reliable and efficient power solutions. Recognizing the growing importance of home energy storage, MORNSUN has directed its efforts towards developing power supply solutions tailored to the needs of this industry.

Take MORNSUN PV75-2YBxxR3 series, home energy storage power supply as a sample,

1. Ultra-low power consumption

The battery continues to consume power even when a home storage device is in standby mode. In civil applications, the standby time is much longer than in industrial applications. Power consumption, i.e. endurance, is a key concern for users. Therefore, in order to ensure that the product consumes less power in standby mode and to improve the overall endurance, the overall standby power consumption of the system needs to be reduced. This also requires the system components to do the same.

PV75-2YBxxR3 is a special power supply for home storage application with ultra-low power consumption performance. The PV75-2YBxxR3 has a quiescent current of only 1mA at 500V input (power consumption 0.5W), which greatly reduces the loss of battery energy in long-term standby mode.

MORNSUN supports the development of the home energy storage industry-4

2. Ultra-wide and ultra-high input voltage range

The power of energy storage devices is generally large, the voltage range of the battery packs unit connected in series is ultra-wide and ultra-high, and the voltage fluctuation range is also large.

The PV power supply takes its power directly from the battery pack unit, so in order to convert this high voltage into usable power, an ultra-wide and ultra-high input voltage range is required for the power module.

PV75-2YBxxR3 series feature an ultra-wide high input voltage range of 80-1000VDC which can meet the requirement of the home energy storage.

3. 1.6 times high transient power

When there may be switching loads, such as contactors, relays, etc., on the back end of the home energy storage system, there will be a short period of high transient current to the power supply and the system will exceed the power supply rating. To prevent damage to the power supply or the protection function from shutting down and causing a system failure, a high transient power supply is required at the front end.

By optimizing the circuit design and component selection for high transient power design, the entire range of MORNSUN PV75-2YBxxR3 series power supplies achieves 1.6 times high transient power, with 75W in steady state and 120W in the transient state for 3s to meet system requirements.

The voltage of the battery pack in a home energy storage system is high. It fluctuates over a wide range. The PV75-2YB12R3, with an ultra-wide input voltage range of 80-1000VDC, is used as the main power supply, drawing power from the battery and outputting 12V to power the display and other units.

The 12V converted into 5V via the back-end non-insolated switching regulator K7805MT-500R4 and fixed input DC/DC converter B0505MT-1WR4, power to the main MCU, and the current and voltage detection system. In addition, the MCU gives the control signal to control the contactor via the IGBT driver to turn the system on and off.


Safety performance, energy density and environmental protection are the core concepts in the development of power supplies for the energy storage industry. Today, MORNSUN’s PV power supplies have been expanded to a power range of 5-1000W and have a range of original patented technologies. They can be applied to the entire system equipment of the PV industry.

Speed and Precision for SiPs

ELE Times - Птн, 12/01/2023 - 13:29

The SIPLACE TX micron is the answer to the challenges manufacturers face in SiP (system-in-package) production. The flexible platform combines the speed of SMT assembly with the complexity of die processing. The new version of the pick-and-place machine has been significantly improved by market and innovation leader ASMPT in terms of speed and placement accuracy as well as transport and processing options. The hybrid system offers electronics manufacturers greater flexibility and thus significant competitive advantages for their Intelligent Factory.

A SiP (system-in-package) combines active and passive electronic components into compact functional groups for things like radio modules in smartphones, wireless earphones, or smartwatches. The advanced packaging technology required for this assembles dies, bare semiconductor chips, as well as classic SMT components. The high demand for such modules can only be satisfied with machines that process dies with the same high speed that is common in the SMT world and with the level of precision that is common in die processing. It involves the placement of passive SMD components, which must often be positioned very close to each other, with exceptional precision.

Two worlds and three precision classes in one machine

The SIPLACE TX micron from ASMPT fully meets these tough industrial requirements of the industry. After a further increase in the machine’s precision, three accuracy classes are now available for advanced packaging applications in a single machine: 10, 15, and 20 microns, each with a process stability of 3 sigma. Despite its improved basic accuracy from 25 to 20 microns, the machine achieves a placement speed of 93,000 cph – an increase of 14 percent compared to the previous 20-micron class of the SIPLACE TX micron. With its maximum placement accuracy of 10 microns, the machine can process an unprecedented 62,000 components per hour even in mixed SiP applications.

Larger components and boards

Thanks to its larger vacuum tooling, the SIPLACE TX micron can now process substrates measuring up to 300 by 240 millimeters with an accuracy of 15 microns @ 3 σ. New as well is the high-resolution SST54 circuit board camera with improved lighting performance for smaller structures, fiducials, and barcodes.

With the Long Board Option, the SIPLACE TX micron can process PCBs measuring up to 590 by 460 millimeters (23.2 by 18.1 inches). Also new is an optional multi-purpose conveyor system that allows regular PCBs, PCBs with carriers up to 20.5 mm high or curvatures as well as J-boats and JEDEC trays to be used as carriers. And customers who manufacture for highly demanding customers like those in the automobile industry will appreciate the optional level of traceability directly from the tape.

Now compatible with SIPLACE Tray Unit

As an added benefit for fast and uninterrupted production, the SIPLACE TX micron can now also be operated with the SIPLACE Tray Unit, which accommodates carriers that can each hold two JEDEC trays. Depending on the size of the components, up to 82 JEDEC trays or 41 wide trays measuring up to 355 by 275 millimeters fit into the unit. As a special feature, new trays can be added without having to interrupt the production because the magazine is split into a buffer zone for the continuous supply and the main storage area, which can be refilled with new trays.

Proven quality

Unchanged in the new version are established features such as the cost-saving detection of damaged or unusable components and the high-resolution component vision system with blue light that improves the image contrast for especially fine structures and balls. The SIPLACE TX micron is also certified in accordance with ISO Class 7 cleanroom requirements and Semi S2/S8.

A safe investment

“ASMPT’s product portfolio covers a wide range of areas for processing dies as well as SMT components,” explains Sylvester Demmel, Senior Product Manager at ASMPT. “To meet the changing market requirements, it was only logical for us to combine these two worlds in one machine, thus giving electronics manufacturers the opportunity to benefit from more flexibility and economic advantages for their Intelligent Factory. With its high precision and maximum placement speeds, the new SIPLACE TX micron is a future-proof investment that is profitable.”

STM32WB09: A new family of STM32WB, a booming beginning for entry-level Bluetooth STM32s

ELE Times - Птн, 12/01/2023 - 09:04

Author : STMicroelectronics

ST is launching today the STM32WB09, thus inaugurating the STM32WB0 series and transitioning the latest generation of BlueNRG-LP(S) devices to the STM32Cube ecosystem. Architecturally, the STM32WB09 is a BlueNRG-LPS with 512 KB of flash instead of 192 KB to allow for more complex applications and an updated radio supporting all Bluetooth LE 5.2 hardware features.

However, in practical terms, the new device is ushering in a new ecosystem that marries existing solutions for STM32WBs and BlueNRGs to create a more productive and cohesive platform. For instance, the STM32WB0s will use the same Bluetooth stack as the BlueNRG-LP(S) while being a full member of the STM32Cube ecosystem. As of today, OEMs have exclusive access to the STM32WB09, and we already set public availability and support for the end of Q2 2024.

Table of Contents STM32WB09: What is happening? The BlueNRG-LP(S) DNA The STM32WB0x

The STM32WB09 shares a lot of its DNA with the BlueNRG-LPS and, as such, uses the same Cortex-M0+ and Bluetooth stack. Integrator creating cost-effective and energy-sensitive solutions will thus inherit the BlueNRG modular software stack geared toward memory footprint optimizations and performance. The stack also stands out thanks to its interoperability and maturity. Similarly, developers enjoy the same advertising extensions, 2 Mbps high-speed, 1.3 km (0.8 miles) unobstructed long-range, and angle of arrival (AoA) or departure (AoD) calculations for position tracking. Moreover, even if engineers benefit from new features, like Isochronous Channels (more on that later), they can still reuse some of the BlueNRG-LPS PCB reference designs.

ST is committing to bringing the existing BlueNRG-LP and BlueNRG-LPS to the new STM32WB0 series. The choice to release the STM32WB09 first stems from a desire to reach partners that are content with the processing capabilities of the BlueNRG-LP(S) but need the memory afforded by some of the dual-core STM32WBs. They work on entry-level applications or energy-sensitive systems that demand the lower power consumption of the BlueNRG-LPS. For instance, the typical current draw of the device in shutdown mode is only 8 nA or almost half that of an STM32WB55. The new STM32WB09 thus gives integrators the ability to enjoy tremendous power savings still while benefiting from vastly more memory.

Over time, ST will also bring some software tools and application demos from the BlueNRG ecosystem to STM32Cube. Customers have shared that some of those tools have helped them optimize their workflow, and we want to ensure that the transition doesn’t rob them of the tools they’ve been relying on. Put simply, we are creating a unified portfolio to ensure developers can move up and down the price-per-performance ladder more easily, making this announcement a pivotal moment for our community.

The STM32Cube ecosystem promised land

The initiative behind the STM32WB0 series partly stems from customers requesting to use the STM32Cube ecosystem with their BlueNRG devices. Hence, the STM32WB09 will enjoy the support of tools like STM32CubeMX and STM32CubeIDE that help with the initialization process. We are also working on updating STM32CubeProgrammer to debug and flash the device and STM32CubeMonitor-RF to optimize RF performances. Consequently, in time, moving from an STM32WBx to an STM32WB0 will be as simple as changing settings in STM32CubeMX and configuring a different pin-out. Applications will thus gain in portability, making Bluetooth systems more accessible.

While we are working on a unified experience, one of the challenges will be to create a cohesive ecosystem that enables developers to port their code from one device to another seamlessly. Similarly, such a massive software transition demands careful planning and extensive support to avoid breaking projects. It’s why we are first working with OEMs and ask that customers contact their ST representative. Working directly with developers will ensure a more efficient transition and smoother experience before we make the STM32WB09 and its STM32Cube ecosystem support available to all.

Why is this happening? The success of the STM32WB

The announcement of the first STM32WB in 2018 was so significant that it disrupted high-end Bluetooth applications. For the first time, the radio and the Cortex-M0+ core driving the wireless stack sat right next to a Cortex-M4, thus allowing developers to create vastly more powerful applications without blowing up their bill of materials. For instance, the Jammy E guitar-shaped MIDI controller wouldn’t have been possible without the STM32WB running the Bluetooth MIDI profile. In fact, the idea of an all-in-one solution became so appealing that we released the STM32WB5MMG soon after. The module houses an STM32WB55, the antenna, baluns, and crystals, further facilitating the creation of powerful Bluetooth systems.

Making cost-effective Bluetooth applications accessible to all

Early this year, we released the STM32WBA, the first wireless Cortex-M33, thus showing our desire to provide powerful and secure systems since the STM32WBA opens the door to a SESIP Level 3 certification. However, teams looking to create more cost-effective solutions significantly favored BlueNRG. The SoCs remain popular, and ST just updated its portfolio to release the smallest BlueNRG-LPS yet at only 6.9 mm2 without compromising features or its +8 dBm power, making them one of the best price-per-feature ratio in the industry. Today’s STM32WB0 series is thus a testament to the success of the BlueNRGs and the STM32WBs as it harmonizes our portfolio while keeping our extensive price umbrella.

The fact that the STM32WB09 also showcases a Bluetooth LE 5.3-certified radio means that engineers get to enjoy features like Isochronous Channels, a new PHY layer that enables more complex data streams by ensuring the transmission of time-sensitive and synchronized information. However, more than adding to a list of specifications, the Bluetooth LE 5.2 radio is symbolic because it shows that besides being cost-effective, like the BlueNRG-LP(S) the STM32WB09 is also cost-competitive like the STM32WBs. Hence, more than a rebranding, the STM32WB09 is a new beginning for the engineers working on Bluetooth applications.

Lm2576 buck converter - massive voltage ripple

Reddit:Electronics - Чтв, 11/30/2023 - 23:51
Lm2576 buck converter - massive voltage ripple

I have a very bizarre issue with the 5v buck converter on a PCB that i have designed.

The first scope image shows a nice stable 5v output given 10 volts input.

Then the second scope image shows some really significant triangular ripple with an average of about 6v.

Then dialling it up to 15 v causes the ripple to get even worse and so on.

Ive put some images in of the PCB and schematic, its using a 220uF aluminium electrolytic on the input and the output as well as a 100uF 2A inductor.

As you can see i was a silly goose and forgot the catch diode (absolutely no idea how) so i soldered one onto the pcb in the appropriate location, however this made no change to the output.

Do you see anything obviously wrong or do you think me running it for a minute or so without a catch diode has frazzled the IC
