Arduino Uno R3 Previous 
Arduino Micro is a compact Arduino Micro board based on the ATmega32U4 microcontroller. It includes a 16 MHz crystal oscillator, a micro USB connection, an ICSP header, and a Reset button. The board provides 20 digital I/O pins, with 7 PWM outputs and 12 analog inputs. It supports USB communication and can be recognized by a computer as a mouse or keyboard, in addition to a CDC serial/COM port. Power can be supplied through micro USB or an external source.
The Arduino Micro is suitable for low-frequency processing projects and for connecting sensors and modules. It combines the core components needed for microcontroller use in a small board format. The board supports operation through a USB connection to a computer or through an external DC supply. Use care when selecting the input voltage to stay within the listed limits.
