About this product
A nano-sized development board by MuseLab built around the WCH CH32V003F4U6 RISC-V microcontroller. It includes a 24MHz crystal, a reset button, an indicator LED, USB Type-C power, and all GPIOs brought out, with a 1-wire serial debug interface (SDI) for programming and debugging. It suits makers who want to prototype with a RISC-V MCU rather than an Arduino-style board.

Frequently asked questions
Is this board Arduino compatible?
No. It uses a WCH CH32V003 RISC-V microcontroller, so Arduino sketches and Arduino-specific boards or libraries will not run on it directly. You need a toolchain that supports the CH32V003; the project documentation on GitHub is the best starting point.
How is the board powered and what should I check before connecting external modules?
The board is powered through its USB Type-C port. Before connecting external 5V devices or sensors, confirm the operating voltage and pin functions on the board silkscreen and in the project documentation to avoid damaging the MCU.
