I am using a vertical microSD card slot, and it does not provide a card detect set of pins.
I have used the card slot with other devices (Pi Compute 3) and I was able to have it auto detect the card was inserted or not, and mount.
Can I configure the same way for the Nano?
(We are not done designing our carrier board yet since we have questions like these).
And if I am not using the SD detect, can I just use that GPIO for something else (assuming I change the PoR functionality of it?)
