Arduino Nano 3.0 is a small, complete, and breadboard-friendly surface mount embedded version of Arduino with integrated USB, which is based on the ATmega328. It has everything that the Arduino Diecimila/Duemilanove has, electrically, with more analog input pins and an onboard +5V AREF jumper. The Nano 3.0 works with a Mini-B USB cable, and can be powered via the Mini-B USB connection, a 6-20V unregulated external power supply (pin 30), or a 5V regulated external power supply (pin 27). The power source is automatically selected to the highest voltage source.
The Nano has the breadboard-ability of the Boarduino and the Mini+USB, with a smaller footprint than either, so users have more breadboard space. It also has a pin layout that works well with the Mini or the Basic Stamp (TX, RX, ATN, GND on one side, power, and ground on the other). This 3.0 version comes with the ATMEGA328, which offers even more programming and data memory space.
