Key Features:
- Stackable to add shields
- 10.5mm long legs
- Multiple pin counts
- Incredibly simple and incredibly useful
What are they for? Stacking. You put the headers on top of your Arduino and then you can add shields like Adafruit's Protoshield or Motor Shield or Proto-Screwshield to get your Arduino doing all the cool things you want it to. 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.
Set includes:
1 - 10-pin header
2 - 8-pin headers
2 - 6-pin headers
1 - 2x3 header
