This cable is a simple 3.5mm mono audio jack on one end, and two alligator clips on the other. Its easy to use with the BBC micro:bit or Adafruit Circuit Playground – just use the two alligator clips to connect to your board and away you go! Plug in your headphones, speakers or even AT (accessible technology) buttons as they use the same 3.5mm mono audio cables for interconnection.

Black wire connects to sleeve, white wire connects to tip.
