Hello,
Unfortunately the USB power port on my Nanopi M4 V2 has broken off and I can't see a way to reattach it securely - it looks like it's just a push fit onto the board on 4 little tabs no solder involved no wonder it eventually fell off. I've heard that it's possible to power the Nano via the GPIO pins - anyone here done that - I'm not to clued up with all things electrical but I can solder ? I'm thinking I could make a cable to connect to the pins.
