Product Reference 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 22 digital
input/output pins, 8 analog pins, and a mini-USB port.

    Power Tree of Arduino Nano The Arduino Nano can be powered by either the USB port or alternatively via VIN. The input supply of VIN is regulated by an LDO so the supply is limited to 5V for the optimal functioning of the board. There is also another regulator which limits the voltage to 3.3V for powrering the components with low voltage requirements.
