The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328P (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.
Nano is an ultra-small Simple i/o platform based on open source code. Compared with the previous USB version of Arduino Diecimila, Arduino Nano has a great advantage in size and has 8 A/D inputs. There are more than 2, and it also has the function of automatic switching between USB power supply and external power supply, which is more suitable for DIY to make more exquisite interactive media works.
