Nano 3.0 Micro-Controller ATMEGA328P with I / O Expansion Shield Module

The Arduino-compatible Nano V3.0 micro-controller is a small, complete, micro-controller board based on the ATmega328P MCU. It has more or less the same functionality of the Arduino Duemilanove, but in a smaller package. It lacks only a DC power jack, and uses a more compact Mini USB (Mini-B) USB cable instead of a standard one.

The Nano IO Expansion Shield is designed to connect and work with ARDUINO Compatible NANO Micro-Controllers. The Expansion Shield Module helps you connect your Arduino-compatible Nano micro-controller to many other devices. It is a perfect companion to the Nano controller and is compatible with both Arduino-compatible Nano v2.x and v3.x.
