I am considering build some of my own shields to interface with the nRF52DK for the 832 and 840. I am curious how I should use header P5 with the shield detect pin. Should my shield pull this pin low?
Thanks, Darren

Hi,
If your shield requires GPIO P0.13 -> P0.20 (The GPIOs used by the buttons and LEDs), the I/O expander can release these for general use by connecting SHIELD DETECT
to ground. You can read more about this here.
Siguard,
Thanks for the clarification!
Cheers, Darren
