Apologies if this is a daft question but why does the On/OFF shim need a power socket? I’d intended to get one for my pi zero and thought I’d be able to simply wire up a button and that would be it. However if I need to power my pi via this new power input, it won’t fit in the case I have.
Therefore, could someone explain the need for a seperate power input? And how it differs from other on/off solutions which simply connect up a switch to pins 5 and 6?
