1. Depends on STM32 Nucleo board solder bridges, see details in
Section 3.3: Solder drop configurations
.
These interrupt signals are duplicated, but not used. This offers hardware connection flexibility in case of
conflict on the MCU interface management when the expansion board is used superimposed with other
expansion boards. In this case, remove the solder drop from the used interrupt and instead, fit the solder
drop in
“NC”.
