The USR switch

Is the USR switch on the pyboard debounced electronically or in the software (micropython)

See the shematic: As far as I know there is no debouncing happening anywhere. You need to do it yourself.

ThomasChr is correct:
See https://github.com/micropython/micropyt ... 32/usrsw.c there's no denouncing there and the schematic has no capacitance across the switch.
