I have possibly the dumbest question. I’m unable to locate a mapping of feather pins to NRF pins for the GPIOs pins - IE Feather pins D2 to D8. The overlay file only defines the AIN and various bus pins.
I have the nRF9160 working so I took a shot in the dark by using the same mapping as the nRF9160. to no success.
Is there a DTS or overlay file where these can be found before the schematic is available?
