There are simply not enough useful GPIO pins on the Blue to be useful
for this application. And the ones that are handed out are in an
inconvenient connector format unless you actually want to connect
servos and stuff. The Blue is specifically designed with a particular
use-case in mind, but it makes it inconvenient in this.

Best is to get a Beaglebone Black or Green if you need GPIOs.
