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 large project. 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).
