The Nano is a small, complete, and breadboard-friendly board based on the ATmega328p.
It has more or less the same functionality of the UNO R3 board, 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. It has 14 digital input/output pins and 8 analog inputs.
