Hi all. I am looking for a way to supply a Pi3B+ with an independent 5volt supply so that I can use/build a safe shutdown backup power supply. I am only really interested in bringing the Pi to a safe sleep state and not to run it for any length of time
Currently the Pi is fed via one or several 5volt gpio pins from an IQAudio Digiamp+ which has a 19volt supply connected to it.
What I am hoping would work is to cut off the 5volt gpio pins through which the digiamp is feeding the 5volts to the Pi.
Anyone got any ideas/views on that?
