The size and pin functions are exactly the same as Arduino Nano.
LDO selection comparison (more than just comparison) hell, I'm very sorry.
The stm32flash parameters of the circuit referring to the punctual atom -i rts,-dtr,dtr
do not support CubeProgrammer automatic connection (because the control method is different).
PlatformIO needs to manually replace stm32flash with a new version to support the G0 series.
You must first manually use CubeProgrammer to connect the SWD configuration nBOOT_SELbit.
At present, it seems that it cannot be automatically reset after downloading, and there is still room for improvement.

Why draw this board? Because I bought some electronic waste from Lao Wang’s family (pictured)
