I’m designing a product that will be battery powered and (hopefully) built using the Fin.
I’m wondering if anybody has implemented an on/off button that gracefully shuts down the board when pushed for off. It’d also be great to have the “hold for x seconds to force shut off” functionality.
Could the co-processor be used for this purpose?
Since my product will be battery powered, drain while off is a concern. Do we know how much power the system consumes when the pi module is shut off?
