Adafruit QT Py CH32V203 Dev Board with STEMMA QT

The Adafruit QT Py CH32V203 Dev Board with STEMMA QT is an ultra-compact RISC-V development board designed for embedded projects, USB applications, and rapid prototyping. Powered by the CH32V203G6 microcontroller running at up to 144MHz, this tiny board combines impressive processing power with the convenience of the STEMMA QT connector for plug-and-play I2C peripherals. Its Seeed XIAO-compatible form factor, built-in RGB NeoPixel, USB Type-C connectivity, and multiple GPIO interfaces make it ideal for makers, advanced hobbyists, and developers working on compact electronics projects. Despite its small size, the board supports UART, SPI, I2C, ADC, and native USB functionality, making it suitable for robotics, HID devices, sensor interfacing, and custom embedded systems.
