This is a SparkFun exclusive! These are 12" long jumper wires terminated as male to male. Use these to jumper from any 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.
