Frequently asked questions
Can I program the CH32V203 using the Arduino IDE?
The listing states Arduino IDE support. You will need to install the CH32 board support package in the Arduino IDE before compiling and uploading code.
What supply voltage and pin mapping should I use?
The listing does not include the supply voltage range or pin functions. Check the WCH datasheet for the exact pin mapping and electrical limits before designing the circuit.
