1. The default state of BOOT0 is 0. It can be set to 1 when a jumper is plugged on the pins 5-7 of CN11.
2. V
REFP
is not connected to CN12 by default (SB20 OFF).
3. 5V_STLK is the 5V power signal, coming from the STLINK-V3E USB connector. It rises before the 5V signal of the board.
4. PA13 and PA14 are shared with SWD signals connected to STLINK-V3E.
5. PG2 to PG15 can be set to different I/O levels, thanks to the SB to select the source for VDDIO2.
