WCH CH32H417 is a high-performance dual-core RISC-V microcontroller clocked at up to 400 MHz with up to 960 KB flash, 896KB SRAM, and a range of interfaces, including a 5 Gbps USB 3.0 Host/Device SuperSpeed interface.
Other notable features include a 500MB/s UHSIF (Universal High Speed Interface), 10/100Mbps Ethernet MAC and PHY, a SerDes high-speed isolated transceiver, a USB 2.0 High-Speed Host/Device, a USB 2.0 OTG Full Speed, USB PD support, and Display and Camera interfaces. The CH32H417 also offers the usual low-speed I/Os (95x GPIO, SPI…) and analog inputs and outputs (ADC/DAC).

Three CH32H417 parts are available with different packages, number of GPIOs, ADC units, touch key channels, and USB features. We can also see a lower-end CH32H415 variant without USB 3.0, Fast Ethernet, and the UHSIF interface.
WCH CH32H417 USB 3.0 Development Board
I first started writing this post in June 2025, or about seven months ago, when Patrick Yang introduced the CH32H417 on X, but when I read the evaluation would become available in about two weeks on AliExpress, I decided to wait for a few more days… However, let’s say there have been delays. The good news is that the board is now available, so let’s have a closer look.
Specifications:
- MCU – WCH CH32H417QEU6 with QFN128 package as described above
- Networking – 10/100Mbps Fast Ethernet RJ45 port
- USB
- USB 3.0 SuperSpeed Type-A port tested up to about 450 MB/s (around 3.6 Gbps)
- USB 2.0 High Speed Type-A port
- USB 2.0 High Speed Type-C port
- Expansion – 4x GPIO headers, including support for the Universal high-speed interface (UHSIF)
- Debugging – SWD Interface for debug & firmware download
- Misc – Reset and User buttons
- Power Supply – 5V via USB-C port
- Dimensions – TBD
You’ll find additional technical details on the product page, where clicking the “More Downloads” button will direct you to the CH32H417 datasheet and QingKe V5 series microprocessor manual in English. The SDK with code samples using the MounRiver IDE and PDF schematics can be found on a separate page, and the technical reference manual (TRM) is only available in Chinese for now.
The CH32H417 evaluation board is currently offered for “pre-order” on AnalogLamb for $19.99, where we’re told the product was officially released on December 31, 2025. If it’s indeed available, it may also show up on WCH’s AliExpress store in the next few days.
