2. The default state of BOOT0 is 0. It can be set to 1 when a jumper is plugged into the pins 5 (VDD) and 7 (PH3
CN7.
3. V is also called ADD on Nucleo-64 because it is the same pin in the LQFP64 package. Connected by default to
REFP
VDD_MCU (SB13 ON). SB13 must be OFF to connect to external VREF from ARDUINO
4. VBUS_STLK is the 5V power signal, coming from the STLINK-V3EC USB connector. It rises before the 5V signal of the
board.
5. PA11 and PA12 are shared with USB signals connected to a USB Type-C
6. PA13 and PA14 are shared with SWD signals connected to STLINK-V3EC (SB29 and SB30 ON).
7. The default configuration for pins 35 and 37 is PA2 and PA3. PA9 and PA10 can be connected instead of PA2 and PA3
depending on the solder bridge configuration.
