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

The Arduino Nano can be powered via the Mini-B USB connection, with 6-20V unregulated external power supply (pin 30) or with 5V regulated external power supply (pin 27). The power source is automatically selected to the highest voltage source.

Notes:

• This is the original Arduino Nano board.
• The package includes only the Nano board, you can find a miniUSB cable and everything you need for your project in our catalog.
