Adafruit Solid-Core Wire Spool - 25ft - 22AWG - Black
Perfect for bread-boarding, free wiring, etc. This spool of solid-core wire is easy to solder to. When bent it keeps its shape pretty well. We like to have a few spools of this stuff around. We suggest picking up wire strippers to match. Wire gauge is 22 AWG which we've found is the best all-around gauge, it works best with breadboards and perfboards but also fits in terminal blocks nicely
