This is a 30cm servo cable.
This comes in very handy when your servo is further away from the controller than the wire on the servo allows.
Female connector on one end goes to controller and the female connector on the other mates with male pins commonly found on a controller board.
This cable does not easily connect to servos but connects great with receivers.
Wire can also be used as a simple 2,54 mm jumper cable.

Includes removable plastic shrouds for both ends.

If you're looking to plug one end of these wires into a breadboard, you could stick our breakaway male headers into the un-shrouded end to make it a true male connector.
