This is a 4 pack of wires that are pre-terminated with an alligator (crocodile) clip on one end and a female header connection on the other. Alligator clips are a staple part for any workbench and with these cables you will be able to easily incorporate those clips into a breadboard, development platform, or anything else that you would normally be able to attach a female jumper connector to.
Each Alligator Clip with female header cable has a wire length of 30cm and a female connector that easily fits onto a standard 2.54mm male connector. Each pack consists of two red cables and two black cables.
These connector wires can also be used to connect a BBC microbit to a prototyping board as an alternative to using an edge connector.
