• Raspberry Pi is in every primary school in Malaysia’s largest state

  It’s really weird to think back to eleven years ago and the modest ambitions that Raspberry Pi founders Eben and Liz Upton had for a green, credit card-sized thing designed to get a few thousand more UK school children into computing. Fast forward to now, and we’re in every single primary school in Malaysia’s largest state.

• Predicting soccer matches with ML on the UNO R4 Minima

  Based on the Renesas RA4M1 microcontroller, the new Arduino UNO R4 boasts 16x the RAM, 8x the flash, and a much faster CPU compared to the previous UNO R3. This means that unlike its predecessor, the R4 is capable of running machine learning at the edge to perform inferencing of incoming data. With this fact in mind, Roni Bandini wanted to leverage his UNO R4 Minima by training a model to predict the likelihood of a FIFA team winning their match.

• Raspberry Pi Radiation Monitor Goes Wireless With Pico W

  The driving module behind this project is a GGreg20_V3 Geiger counter module. This device is able to detect radiation levels with data that can be read by separate modules like a Raspberry Pi Pico W. In this case, Sboger is using ESPHome to receive data from the Pico W and process it into a useful gauge graphic.

• Much Better VGA From An ESP32

  The ESP32 series from Espressif have been a successful line of products, offering a powerful microcontroller with on-chip wireless networking. There’s a snag though in their practice of calling all of them ESP32s despite wildly varying specifications and even different processor cores, such that it’s easy to lose track of exactly what the chip in front of you can do. [Bitluni] was faced with updating his VGA library to include a newer variant, and was pleasantly surprised to find that it includes a far more capable display peripheral which enables significantly higher resolutions than previously.

• The Core3566 module is compatible with the Raspberry Pi CM4

  Waveshare Electronics recently featured a computer module that combines versatile features with a compact form factor. The Core3566 integrates a Rockchip RK3566 processor running at 1.8GHz and a 0.8 Neural Processing Unit.

• Aries Embedded launches MSMP1 SiP for industrial IoT applications

  Aries Embedded recently launched the MSMP1 that meets the Open Standard Module (OSM) guidelines. This embedded product is built upon the architecture of STMicroelectronics STM32MP1 family and offers a robust computing solution with single/dual Cortex-A7 cores along with a Cortex-M4 coprocessor.
