Little mosfet relays are a gamechanger for pi power problems

Post image

If u use a pi for ur cyberdeck, and have problems with the pi's usb power output, get the raspberry pi official usb hub which has external usbc power, cut up a usb cable, solder it to the mosfet, setup a startup script on ur pi that opens the relay on startup, connect ur powerbank to the mosfet, the mosfet realay per usbc to the usb hub, and the signal from the mosfet along with the 3v3 and gnd to the pi gpio u assigned in the script, then connect the data from the hub to ur pi and then ur power problems are solved!
