Arduino Micro
Small, smaller, & smallest is the order of the day and Arduino
Micro holds true to the modern-day technological preferences. This tiny
board makes it possible to integrate various objects to interact with the
board. Featuring the ATmega32U4 in addition to the built-in USB, the Micro is
an innovative release from Arduino. The USB (Built-in) helps the board to
connect just like a keyboard or a mouse.

Arduino Micro Description
The Micro is equipped with full support which is required to help the
microcontroller perform at its best. You only need a micro USB to establish the
connection with the computer. The form factor is highly suitable in accordance
to the breadboard requirements.
As far as the microcontroller and built-in USB are concerned, the Micro
is same as the Arduino Leonardo. You don’t need a secondary processor to
support the board. It enables the board to be identified just like the
plug&play devices.
Warning from Arduino
To deal with the overcurrent and short-circuits, the Micro features a Polyfuse (resettable) to protect USB ports.
Regardless of the fact that most of the computers come with the protection
system against overcurrent, Polyfuse
serves as an additional protection. You need to be mindful of the fact that
over 500mA will force the Polyfuse to
break the connection.
