Good value but docs could be better

The board itself is solid. Documentation is improving but sometimes hard to find in English.

Reliable microcontroller module

Stable performance during testing. The SWD interface works smoothly with WCH-LinkE debugger.

5 FAQ

Q: Which debugger do you recommend?

A: The WCH-LinkE or WCH-LinkSV is recommended for programming and debugging.

Q: Is there an onboard voltage regulator?

A: This is a core board, it typically requires 3.3V input directly. Please check the schematic.

Q: Does this work with Arduino IDE?

A: Yes, there are community cores available for Arduino IDE support.

Q: Where can I find the pinout diagram?

A: The datasheet and pinout diagram are available on the manufacturer's website or our product description tab.

Q: Can I use this for 5V logic?

A: No, this is a 3.3V logic device. Use level shifters for 5V peripherals.
