ELECTRICAL CHARACTERISTICS
5.1.
Absolute Maximum Ratings
Stresses beyond those listed under
“Absolute Maximum Ratings” may cause permanent
damage to the device. These are stress ratings only and functional operation of the device
at these or any other conditions
beyond those indicated under “Electrical Requirements”
is not implied. Exposure to absolute-maximum-rated conditions for extended periods
may affect device reliability.

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
