There are 20 digital I/O pins (7 of them can be used as PWM out, 12 of them can be used as analog input), 16 MHz crystal oscilator, micro usb socket, power socket, ICSP connector and a reset button on the board. There are everything for the microcontroller to work on the board. The board can be easily connected to a computer via usb, can be supplied with an adapter or a battery.

Leonardo board is seperated from other boards by using ATmega32u4 microcontroller, Atmega32u4 is able to communicate with a computer directly thus it does not need an USB - Serial converter. Thanks to these features, Leonardo can be introduced to computer as not only virtual COM port but also as peripherals such as console and mouse too.
