CNX Software ☛ SparkFun RTK EVK offers GNSS with centimeter accuracy, WiFi, Bluetooth, 4G LTE Cat 1, and Ethernet connectivity
SparkFun RTK EVK is a fully-enclosed GNSS platform designed for fixed or mobile high-precision positioning and navigation applications with centimeter accuracy thanks to RTK (real-time kinematic) technology implemented with modules from u-blox. About two months ago, Sparkfun introduced the RTK Torch waterproof GNSS surveyor with Unicore UM980 GNSS module with RTK support, ESP32 for WiFi/Bluetooth, and an STM32WLE5C LoRa SoC.

CNX Software ☛ Rockchip RKLLM toolkit released for NPU-accelerated large language models on RK3588, RK3588S, RK3576 SoCs
Rockchip RKLLM toolkit (also known as rknn-llm) is a software stack used to deploy generative Hey Hi (AI) models to Rockchip RK3588, RK3588S, or RK3576 SoC using the built-in NPU with 6 TOPS of Hey Hi (AI) performance. We previously tested LLM’s on Rockchip RK3588 SBC using the Mali G610 GPU, and expected NPU support to come soon. A post on X by Orange Pi notified us that the RKLLM software stack had been released and worked on Orange Pi 5 family of single board computers and the Orange Pi CM5 system-on-module.

Arduino ☛ Ride safer with these DIY bicycle lights
Many people around the world live in cities designed for cars, with bicycle use being a distant afterthought. That makes cycling dangerous and lights can do a lot to make riding safer. That’s why Giovanni Aggiustatutto designed this DIY system that includes headlights, a taillight, turn signals, and even an integrated odometer/speedometer.
