The Arduino Nano is a small board based on the ATmega328 or 168. It has male headers, so it can be plugged directly into a breadboard. It is small and compact, and features a USB chip.

The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.x) or ATmega168 (Arduino Nano 2.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. The Nano was designed and is being produced by Gravitech.

What is the maximum power consumption of the Arduino Nano 3.0?

What is the maximum power consumption (in mW) of the Arduino Nano 3.0, when it is running in its default state (at 16MHz, no LEDs removed) and powered by an external regulated 5V supply so it bypasses the built in voltage regulator? This will give…

How to change baudrate of ESP8266 (12e) permanently?

IMPORTANT: DO NOT USE AT+IPR=9600! (see update) I have an ESP8266 12E module that communicates at 115,200 bauds. Since I use it with an Arduino Nano with SoftwareSerial things get messy. So I found that I should reduce the baud rate of the ESP…

Why are the pin numbers of the diagrams and of the code different?

If I search Google for "arduino nano pin numbers", all results show that the pin number of D2 is 5. But that did not work. I searched for some sample codes, and they were 3 for D3 and 5 for D5, etc. So, in codes, the pin number for Dn is n. Then…

Are there any reasons to pick Nano over Micro?

Nano is from 2008, and micro from 2012. Micro seems better on every parameter, in particular in having a better (I think) microcontroller, ATMega32u4, over ATMega328P. However, all the shops I've checked out, both local and online, sell the Nano,…
