It is the smallest member of the Arduino family. Developed in collaboration with Adafruit, the Arduino Micro is an ideal platform in many projects. Built around the ATmega32U4 micro-controller (datasheet), it has 20 digital inputs / outputs (including 7 PWM) and 12 analog inputs.

- Documentation
We find Asian clones of the Arduino Micro. The Arduino Nano v3 built from the Atmega328P has 16 I/O (instead of 20) and 8 analog inputs (instead of 12). Fewer inputs / outputs, but a much lower price as well. Count 1.80 € from China instead of 18 € for the official version!
Attention, there are also Arduino Pro Micro based ATMEGA32U4 even more compact (only 4 analog inputs and 12 I / O). It is recognized as an Arduino Leonardo by Arduino IDE.
