CH32V003 RISC-V Microcontroller Development Board – USB-C

CH32V003 RISC-V Microcontroller Development Board – USB-C

Meet the CH32V003 Development Board — a compact, ultra-affordable RISC-V based microcontroller board that packs serious capability into a tiny footprint. Powered by the WCH CH32V003 chip running the open-source RISC-V instruction set architecture, this board is perfect for makers, students, and embedded developers looking to explore RISC-V beyond the mainstream.

With a modern USB-C interface, labeled GPIO breakout pins, and a built-in reset button, it's ready to program right out of the box using the MounRiver Studio IDE or compatible toolchains.
