These extremely tall breadboard compatible 0.100″ breakaway headers are great when you need some serious space between boards! Breakaway Headers are a great way to connect small perf-boards or breakout boards to a breadboard or other 0.100″ pitch board. The headers ship as a single 40 pin piece that can easy be snapped apart to any length required. One end with shorter pins will typically be soldered into a circuit board while the side with longer pins will fit into standard Female headers.
