These are 6″ long jumper wires with male connectors on both ends. Use these to jumper from any female header on any board, to any other female header. Combine these with our female to female jumpers to create a male to female jumper. Multiple jumpers can be connected next to one another on a 0.1″ header. Comes in one pack of 20 jumpers (colors shown). Each group of jumpers are connected to each other and can either be pulled apart in any quantity (from 1-20, of course) or kept whole based on you needs.
These jumper wires can be used for pretty much everything! They work great with breadboards, Arduinos, and really any 0.1″ pitch prototyping board.
