5.4 DC Parameter
All Module I/O pins are connected directly to the Nordic nRF52832 chip without signal
conditioning except for some pull-up/pull-down resistors (as indicated). Therefore the
electrical characteristics are as documented in the Nordic nRF52832 data sheet Nordic:
nRF52_Series_Reference_Manual.
