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?

 

I normally use 30AWG wire-wrap wire for connections. You can use enameled copper wire if you scrape off the enamel at the ends. You can get similar wire where the heat from the soldering process will burn off the plastic coating.

 

If you can find some Beldsol magnet wire, you will be able to melt away the insulation with your soldering iron -no scraping, filing, or sanding necessary. Very convenient, but Beldsol is not highly resistant to abrasion.

 

Thanks guys! I tried the magnet wire and it seems to be working well. I half scraped and half burned off the enamel.
