This port is used for both programming and serial monitoring. The Nano board doesn’t have a DC power jack as other Arduino boards, but instead has a mini-USB port. The extra 2 pins of Arduino Nano serve for the ADC functionalities, while UNO has 6 ADC ports but Nano has 8 ADC ports.

The main difference between them is that the UNO board is presented in PDIP (Plastic Dual-In-line Package) form with 30 pins and Nano is available in TQFP (plastic quad flat pack) with 32 pins. The Nano is inbuilt with the ATmega328P microcontroller, same as the Arduino UNO. How different is Arduino Nano?Īrduino Nano has similar functionalities as Arduino Duemilanove but with a different package.

This article discusses about the technical specs most importantly the pinout and functions of each and every pin in the Arduino Nano board. The Nano board weighs around 7 grams with dimensions of 4.5 cms to 1.8 cms (L to B).

The Arduino Nano, as the name suggests is a compact, complete and bread-board friendly microcontroller board.

We’ve created a well explained, diagram based pin out representation of Arduino Nano. In this guide, learn about Arduino Nano pin outs and diagrams.
