CAPUF Embedded CH32V003 Dev Kit is an all-in-one development board with a USB-C interface, onboard sensors (temperature/humidity), an OLED display, SPI NOR Flash, and ample I/O options. Additionally, it features a Qwicc connector, an RGB LED, and a 3-pin header to connect the WCH-link programmer providing further flexibility for your projects.
After the initial release of this “10 cents” CH32V003 RISC-V microcontroller, we have seen $1.5 development boards and an open-source GGC toolchain, as well as Arduino support for the WCH RISC-V microcontrollers. Very recently, CNLohr even managed to transmit LoRa packets with this MCU.

Inside the box, you will find a CH32V003 Dev Kit Development Board, a USB-A to USB-C cable, and a WCHLinkE programmer. Additionally, the company will provide resources such as a PDF schematic and a Dev Kit 3D model, which are currently unavailable at the time of writing. The company also provides a getting started guide with real-world examples on its website and code samples can be found on their GitHub repository.
The product is not yet available for purchase. However, the product page indicates that it will be released soon. Back in December 2023, CAPUF Embedded told CNX Software the board would be available soon for approximately 35-45 USD with free shipping worldwide.
