Designed by MuseLab, the nanoCH32H417 is a development board for the WCH CH32H417 dual-core RISC-V MCU, which we covered earlier this year for its USB 3.0 (5 Gbps), UHS, and Fast Ethernet support. At that time, only the official CH32H417 development board was available, but this board adds a third-party option.
The board exposes various features of the MCU, including one USB 3.0 port, two USB Type-C ports, a 100Mbps Ethernet interface, and a MicroSD card slot. It also simplifies the prototyping workflow by integrating a WCHLink-E debugger directly onto the board, meaning you won’t need to wire up an external programmer to flash the MCU or view serial output.

WCH MCUs can generally be programmed with the MounRiver Studio IDE (MRS), and this is no different. MuseLab has provided a GitHub repository that includes the PDF schematics, English and Chinese documentation, and a basic GPIO toggle project to help verify your toolchain setup before moving on to testing the USB 3.0 or Ethernet stacks. If you prefer an open-source GCC toolchain, the ch32fun project‘s code has a few references to ch32h41, so it might work, although it’s not been added to the list of supported WCH MCUs yet.
The MuseLab CH32H417 development board is available on AliExpress, with prices ranging from $21.49 to $25.50 depending on the configuration, as well as on the company’s Tindie store starting at $17.00. The base variant includes the board and the 13-pin headers. They also offer several bundle options, including a 1.54-inch (240×240) screen for $20, with additional USB 3.0 Type-A and Type-C cables available for a few extra dollars.
