If you’ve already got a Raspberry Pi and need more I/O or you’ve got an Arduino Due and want more processing speed then the BeagleBone Black may be what you’ve been looking for. In this our first .Post on the Beagle- Bone Black (or just BBB) we’ll be looking at its hardware expansion capabilities. After we looked at its hardware we’ll write ourselves the traditional “Blinky” LED program as our first program.

The BBB is seriously equipped for your hardware projects. It has a doggy bag full of GPIO, analogue, PWM and serial interfaces. The BBB has two expansion headers, P8 (Expansion B) and P9 (Expansion A) with each header is a 46-pin hobbyist friendly 0.1” pitch female header.
