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)
If you used Arduino Nano in your projects in the past, the Nano Every is a pin-equivalent substitute. 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
