The nanoCH32V317 from MuseLab is a low-cost RISC-V development board designed for prototyping embedded systems and education. Built around the 144MHz WCH CH32V317WCU6 MCU. This development board is suitable for various embedded, IoT, prototyping, and automation projects.
Other features of the development board include a USB 2.0 high-speed and full-speed controller, a 10/100Mbps Ethernet MAC with PHY, SDIO, and a DVP interface for digital video input, as well as advanced motor PWM timers for control applications. The board also includes an 8MHz main crystal and a 32.768KHz RTC crystal. For programming, it includes a dual USB Type-C interface, a USB ISP, as well as an SWD port.

In terms of software support, the nanoCH32V317 development board can be programmed with WCH’s MounRiver Studio IDE, which works with Windows, Linux, and macOS environments. The IDE is optimised for WCH’s RISC-V architecture, and you can build, compile, and debug applications using C/C++. Firmware can be programmed via WCHISPStudio over the USB interface or through SWD using the WCH-Link debugger. More information, along with example projects, reference manuals, schematics, and peripheral libraries, is available on nanoCH32V317’s GitHub repo.
Previously, we have seen WCH’s CH32V307 MCU become very popular thanks to its low cost, diverse peripherals, and ease of use, and we have seen various RISC-V development boards based on WCH microcontrollers, such as the CH32-Ant dev board, the Phyx LANA-TNY, and the CAPUF Embedded CH32V003 Dev Kit, but this is the first time we have seen a development board for the CH32V317 MCU, which features an Ethernet PHY, dual USB, SDIO, and DVP support.
The nanoCH32V317 development board is available on AliExpress starting at $8.07 for the board only. A bundle with a USB Type-C cable and a WCH-LinkE debugger is priced at $13.31, and additional discounts are available for bulk purchases. It’s also listed on the company’s Tindie store with similar bundle options, but at slightly lower prices.
