What are they for? Stacking. You put the headers on top of your Arduino and then you can add shields like our Protoshield or our Motor Shield or our Proto-Screwshield (pictured above) to get your Arduino doing all the cool things you want it to. Our set includes 1x 10-pin header, 2x 8-pin headers, 2x 6-pin headers, and one 2x3 header. The legs are all 10.5mm long, so after PCB thickness (1.7mm) you have a height of 8.8mm - just enough to clear the Arduino s USB-B connector. They re also fully compatible with shields designed for Arduino R3 and the Leonardo. For shields that don t use the 10-pin header or 2x3 header, use the 6 or 8 pin ones.
