The Otto Nano PCB is Arduino’s 5V compatible board in the smallest available form factor: 40x40mm!
This is the new preferred board for many robot projects requiring a small and easy to use microcontroller board. The small footprint and low price, make the Otto Nano particularly suited for wearable inventions, low cost robotics, electronic musical instruments, and general use to control smaller parts of a larger projects.
The Otto Nano is an evolution of the traditional Arduino Nano board, but features easier to understand and fast connections with its colored pins, power JST connector for our new rechargeable battery and a micro USB connector
An Improved Arduino Nano
If you used Arduino Nano in your projects in the past. 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 compact size and a micro-USB connector.
