Pin distribution diagram
Thanks, Richard·Balint !!
With the pin allocation diagram, it's easier to work with MicroPython and Arduino!
Method 1: When the power is on, press the BOOT0 key and the reset key, then release the reset key, and release the BOOT0 key after 0.5 seconds
Method 2: When the power is off, hold down the BOOT0 key, and release the BOOT0 at 0.5s after the power is on
DFU Mode: Use the data line to connect to the computer. If there is an unrecognized problem, you can heat the chip appropriately (25°C) and then re-enter the ISP mode
Serial Port Mode: Connect PA9 and PA10 of core board with USB serial port
