This is a SparkFun exclusive! These are 12" long, 26 AWG jumper wires terminated as male to female. Use these to jumper from any male or female header on any board. Multiple jumpers can be connected next to one another on a 0.1" header. Comes in five packs of twenty jumpers (colors shown).
We use these wires for everything! They work great with breadboards, Arduinos, and really any 0.1" pitch prototyping board.
