I'm a newby in the field of Electrical Engineering (only basic knowledge from school). Nevertheless, I need to power up to 10 Raspberry Pis (5V, 2A) with Dupont Connectors and AWG24 cables over GPIO header. I have a power supply unit giving me max 30A at 5V.
My question is, can I just etch e.g. two lanes on a PCB and solder a Dupont header (10 by 2) with 10 output pairs (each for one device) to them and powering those lanes at the end with one input pair coming from the psu (with stronger wire gauges, maybe AWG18)? Of course I would apply solder masking, to prevent short circuits and oxidation.
This seems a bit naive, so I'm asking your opinion. Maybe you are aware of other neat solutions?
