Arduino Nano V3 ATmega328 Development Board

Arduino Nano V3 ATmega328 Development Board is a small, complete, and breadboard-friendly board. The board is 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.
