Arduino IC-9700 Contest Keyboard PCB only

The IC-9700 Contest Keyboard is a small Arduino-based circuit that allows an old PS2 keyboard to remotely drive an IC-9700 or in theory any Icom radio with a CI-V interface. It allows quick and easy access to many functions of the radio, as well as 12 pre-set frequencies with a single keystroke. It has 3 connections. +12v, a 3.5mm cable to connect to the CI-V port on the radio, and a PS2 keyboard.

See the IC-9700 Contest Keyboard blog post to download the sketch as well as more information including the parts list.

The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.x). It has more or less the same functionality of the Arduino Duemilanove, but in a different package. It lacks only a DC power jack and works with a Mini-B USB cable instead of a standard one.
