Arduino® Nano User Manual
SKU: A000005 Description
Arduino® Nano is an intelligent development board designed for building faster prototypes with the smallest
dimension. Arduino Nano being the oldest member of the Nano family, provides enough interfaces for your
breadboard-friendly applications. At the heart of the board is ATmega328 microcontroller clocked at a frequency
of 16 MHz featuring more or less the same functionalities as the Arduino® Duemilanove. The board offers 20 digital
input/output pins, 8 analog pins, and a mini-USB port. Target Areas
