Stackable Header Kit For Arduino Shield
These headers are made to work with the Arduino Uno R3, Leonardo, and new Arduino boards going forward. They are the perfect height for clearing the USB-B connector and great for stacking multiple shields. This kit includes 4 headers (2 8-pin, 1 10-pin, 1 6-pin, and 2x3-pin), enough to connect a shield to an Arduino board. These are the same headers we use with our own shields.
