1. These interrupt signals are duplicated, but not used by default. This offers hardware connection of the breakout board
VL53L1 interrupt signals and flexibility in case of conflict on the MCU interface management when the expansion board is
used superimposed with other expansion boards. In this case, select, through a solder drop, the MCU port which is free.
