We even wrote a very nice library for the backpacks so you can get running in under half an hour

it's still the best and sleekest way to protect your precious Beagle Bone Black

Digits have seven yellow segments on a black surface and we give you a set of two alphanumeric displays as well as a driver board so you can make a clock or a four-letter word

A fun way to make a small display is to use an 8x8 matrix or a 4 digit 7 segment display. Matrices like these are 'multiplexed' so to control all the seven segment LEDs you need 14 pins. That's a lot of pins, and there are driver chips like the MAX7219 that can control a matrix for you but there's a lot of wiring to set up and they take up a ton of space. Here at Adafruit, we feel your pain! After all,
