A 83 key keyboard, Norwegian QWERTY/DVORAK ISO style. It's of course possible to use other languages, as the MX cherry switches will accept keycaps with whatever language you need. It uses 83 1N4148 diodes and three LED's for caps lock,scroll lock, and QWERTY/DVORAK. It also needs pin headers that accepts the pins from a Teensy++2.0
