Can I use Dupont wires for power delivery?
Most of dupont jumpers are 28 AWG. This means that the max permissible current is around 1 Amp. However, some dupont jumpers, especially the Chinese ones, are not really 28 AWG even if they look so. Maybe you can use 2 or 3 of them paralleled, just in case.
PS: The other day I had to cut one of them for MCU-programming purposes. What I saw inside the insulator was only 5 or 6 pieces of ~0.1mm-dia conductors. I'd think twice before using them for &gt;1A currents.
