Silicon Labs has announced the BG29 family of Bluetooth Low Energy (BLE) wireless microcontrollers, suitable for wearables and even smart teeth implants, featuring an Arm Cortex-M33F core, up to 1MB of flash storage, and a variety of peripherals.
Glowtape is a unique DIY wristwatch by Henner Zeller that uses glow-in-the-dark tape and an RP2040 microcontroller to display the time.
Open-source project showcasing a speech-to-text application on a low-cost CH32V003 microcontroller. The application reads audio from an analog microphone, identifies spoken digits 'zero' to 'nine', and logs the results over a serial link.
emlearn is an open-source machine learning inference engine designed for microcontrollers and embedded devices. It supports various machine learning models for classification, regression, unsupervised learning, and feature extraction. The engine is portable, with a single header file include, and uses C99 code and static memory allocation. Users can train models in Python and convert them to C code for inference.
