1. Depending on Nucleo board solder bridges, see details on Nucleo documentation. These interrupt signals
are duplicated, but not used, this offers hardware connection flexibility in case of conflict on MCU interface
management when expansion board is used superposed with other expansion boards, in this case
remove 0 ohm resistor from interrupt used and connect 0 ohm resistor in place of “do not mount” one.
