Great value, minor documentation gaps
Hardware performance is top-notch for the price. Flashing via WCH-Link was seamless. Would give 5 stars if the English datasheet had more examples for the DMA controller.

Perfect for learning RISC-V
Switched from ARM to this board for a university project. The MounRiver Studio IDE works well, and the community support is growing fast. Highly recommended for students.

Excellent RISC-V board for embedded projects
This CH32V307 board is fantastic. The clock speed of 144MHz handles my RT-Thread applications smoothly. Pinout is clearly labeled and the build quality is solid.

Fast delivery and good performance
Board arrived quickly and worked out of the box. The USB peripheral setup took some time to configure correctly, but once running, it performs exceptionally well.

Robust for industrial control prototypes
Used this for a motor control prototype. The CAN bus implementation is stable, and the ADC resolution is sufficient for our sensor readings. Very impressed with the stability.

Best budget RISC-V dev board
Unbeatable price for the specs. 480KB flash is plenty for most IoT applications. The pin headers make it easy to plug into breadboards or custom PCBs.
Q: Is this compatible with Arduino IDE?
A: While primarily designed for MounRiver Studio, there are community-maintained cores that allow programming via Arduino IDE, though official support is focused on MounRiver and standard C SDKs.
Q: Are the pin headers pre-soldered?
A: Yes, the standard version of this core board comes with male pin headers pre-soldered on both sides for immediate use in breadboards or sockets.
Q: Does this board come with a debugger included?
A: No, the core board does not include a debugger. You will need a separate WCH-Link or compatible JTAG/SWD programmer to flash and debug code.
Q: What is the current consumption in sleep mode?
A: In stop mode, the current consumption is typically in the microampere range (approx. 5-10 µA depending on configuration), making it suitable for low-power battery applications.
Q: Can I use this board for USB Host applications?
A: Yes, the CH32V307 supports USB OTG, allowing it to function as both a USB Device and a USB Host with the appropriate software stack configuration.
