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 and 1 6-pin), enough to connect a shield to an Arduino board. These are the same headers we use in our tutorials and with our own shields. **Note:** If you have a board that does not use the Arduino R3 architecture which include the OREF, SCL, and SDA pins they can be found [here](https://www.sparkfun.com/products/10007). We know that many boards still do not use the R3 layout so we like keeping that kit available for those situations! **Includes:** * [2x - 8-pin Arduino Stackable Headers](http://www.sparkfun.com/commerce/product_info.php?products_id=9279) * [1x - 6-pin Arduino Stackable Headers](http://www.sparkfun.com/commerce/product_info.php?products_id=9280) * [1x - 10-pin Arduino Stackable Headers](https://www.sparkfun.com/products/11376) **Documents:** * [Mechanical Drawing](https://cdn.sparkfun.com/assets/3/f/3/2/1/SP-140520-XX-001.pdf)
