Note: this only works with shields designed for the Arduino Uno R3, Leonardo and new Arduino boards going forward (10-8-8-6-pins). Some of the older shield still have the 8-8-6-6-pins configuration. In which case, you need the 8-8-6-6 stackable header. Please check the 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 (1x 8-pin, 1x 10-pin and 2x 6-pin), enough to connect a shield to an Arduino board. The pitch is the standard 0.1" used with breadboard and protoboard.
