Arduino Nano v3.1

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. The Nano was designed and is being produced by Gravitech. See here for the main Arduino Nano Information page! Arduino Nano 3.0 (ATmega328): schematic, Eagle files.
