Hi everyone,
In the PineTime schematic v1.0, the main button (J6 KEY) is connected to the nRF52832 MCU pins P0.13 and P0.15, both circuits are pulled-down externally and receiving VCC33 when key is pressed.
I can not figure out the motivation to use 2 MCU pins to control the key. May be is it intended to detect whether the key is there, in the case?
Regards,
Rafa
