Nano Every-board

Nano Every

The Nano Every is Arduino's smallest board with dimensions of only 45x18mm and a weight under 5gr. The small footprint and low price, make the Nano Every particularly suited for wearable inventions, low cost robotics and interactive projects requiring a small and easy to use microcontroller board.


The Arduino Nano Every is an evolution of the classic Arduino Nano sharing the same exact pinout but featuring the ATMega4809, a more powerful processor as well as 48KB of CPU Flash memory and a higher clock speed of 20 MHz.

ATMega4809 microcontroller

The ATMega4809 CPU features 50% more program memory than the classic Arduino UNO, allowing for larger programs.

Nano Form Factor
Tiny footprint

With a length of 45 mm and a width of 18 mm the Nano Every is Arduino's smallest board, weighing only 5 grams with attached headers and even less when configured without them.
