Compare Arduino Nano

The Arduino Nano is the first board in this family. It has been a reliable and popular board for years. The Arduino Nano is comparable to the Arduino Uno . It was therefore a logical step for many to use it for projects where an Arduino Uno simply does not fit. Because you can place the Arduino Nano directly on a breadboard, it is easy to make your project even more compact.
The Arduino Nano has 22 digital, 6 PWM and 8 analog pins.
