Board has 3 buttons BOOT0/RESET/KEY(USER PA0) & 2 LEDS -RED=PWR, BLUE=USER (PC13)
Program using SWDIO/SWCLK & STLINK/JLINK/DAPLINK debugger/programmer
OR connect USB-C to computer & use DFU fw update mode (either method can be used with Arduino IDE)
DFU Method 1: Press and hold the BOOT0 button, then press & release the reset button, wait another 0.5 seconds then release the BOOT0.
DFU Method 2: Hold down the BOOT0 key when power is off, and release the BOOT0 key 0.5S after power on.
No need for USB to serial port, no debugger, no computer driver, just a TYPE-C data cable to complete the firmware download
