This is a 4 pack of wires that are pre-terminated with an alligator (crocodile) clip on one end and a hookup pigtail (male jumper connector) 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 male jumper connector to. Each Alligator Clip with Pigtail cable has a wire length of 30cm (that’s a little less than 1ft) and a male pin that easily inserts into a standard 0.1" 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 an edge connector. Features: Wires with a croc clip on one end and a male jumper cable connector (pigtail) on the other. Enables you to connect a BBC microbit to a prototyping board as an alternative to using an edge connector.
