This 2x20 \"tall\" header has the same number and spacing of pins as a Raspberry Pi and provides your board with the ability to extend the heights of your GPIO to accommodate for enclosures or other parts that can encapsulate your Pi. This through-hole header has 40 0.1\"-spaced pins and can just be snapped into place with minimal soldering to an applicable \"shield.\" **Documents:** * [Dimensional Drawing](https://cdn.sparkfun.com/datasheets/Dev/RaspberryPi/12313.pdf)
