Sunfounder Nano is created by the purpose of repairing a defect on the Arduino Nano, it is the same in general and can replace the Arduino Nano 3.0.
The Sunfounder Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3. x) or ATmega168 (Arduino Nano 2. 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.
