1 × Arduino Nano / Atmega 328p+FTDI circuit The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (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.
1 × Power circuit It includes a system DC/DC which supply 5V to the circuit thanks to a lithium battery.
