Perhaps an odd question but I am trying to cram a bunch of stuff into an altoids mini's tin and the hookup wire itself is taking up a lot of space. I was thinking of using magnet wire. Basically it will be an arduino pro mini connected to a couple of peripherals that it will be communicating with (spi and uart). The magnet wire will minimize the amount of space needed by the hookup wires. Is there any reason not to use magnet wire for this application?
