The Arduino Nano. It has always been popular for Arduino projects due to its tiny footprint and also reliability which allows it to be integrated into many projects like wearables, mini robots and many more!

Through this blog, I will be covering:

  • Introduction to Arduino Nano v3
  • Seeeduino Nano – Alternative to the Arduino Nano
  • 20 Best Arduino Nano Projects that you must try 2019

Introduction to Arduino Nano v3

  • The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.0).
  • It offers similar connectivity and specs of the Arduino Uno Rev3 and lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one.
  • Based on the ATmega328P the Arduino Nano is good for beginners to start on the Arduino!
    • To know more about the ATmega328P, you can check out our other blog here!

Seeeduino Nano – Alternative to the Arduino Nano

Feel that the Arduino Nano is too expensive and looking for an alternative? No worries, as Seeed got the solution for you with our Seeeduino Nano:

  • The Seeeduino Nano is a compact board which is fully compatible with the Arduino Nano on pinout on sizes.
  • The first you will realise about the Seeduino Nano is the price of it. It only costs $6.90 which is 6 times cheaper than the Arduino Nano!
  • Afraid that the specs will be compromised due to the low cost? No! Not only does the Seeduino Nano offer the same features and high-quality experience as the Arduino Nano, we have also made some improvements on it which are:
    • Mini – USB to Type -C which is symmetrical and reversible
    • Addition of 1 Grove Connector where with the help of our Grove system, you can easily plug and play with hundreds of sensors and actuators.
  • Here is a table comparing both of them!
