The VMA102 is an Arduino-Compatible Nano 3.0, which is a small, complete, and breadboard-friendly microcontroller board based on the ATmega328 (Arduino Nano 3.x). It has pretty much the same functionality of the Arduino Duemilanove, but in a much more compact package. It lacks a DC power jack but can be powered with a mini-B USB cable instead of a standard one.
100% compatible with Arduino® Nano v3.0

Operating voltage: 5 VDC
Input voltage (recommended): 7-12 VDC
Input voltage (limits): 6-20 VDC
