The Nano Every is Arduino’s 5V compatible board in the smallest available form factor: 45x18mm! 

The Arduino Nano is the preferred board for many projects requiring a small and easy to use microcontroller board. The small footprint and low price, make the Nano Every particularly suited for wearable inventions, low cost robotics, electronic musical instruments, and general use to control smaller parts of a larger projects.

 The Arduino Nano Every is an evolution of the traditional Arduino Nano board, but features a lot more powerful processor, the ATMega4809. This will allow you to make larger programs than with the Arduino Uno (it has 50% more program memory), and with a lot more variables (the RAM is 200% bigger). 

An Improved Arduino Nano 

If you used Arduino Nano in your projects in the past, the Nano Every is a pin-equivalent substitute. Your code will still work, and you will NOT need to re-wire those motors you planned in your original design. The main differences are: a better processor, and a micro-USB connector.

 The board comes in two options: with or without headers, allowing you to embed the Nano Every inside any kind of inventions, including wearables. The board comes with tessellated connectors and no components on the B-side. These features allow you to solder the board directly onto your own design, minimizing the height of your whole prototype.
