Arduino Leonardo ATmega32U4 Development Board

Arduino Leonardo is Arduino’s first development board to use one microcontroller with built-in USB. Using the ATmega32U4 as its sole microcontroller allows it to be cheaper and simpler. Also, because the 32U4 is handling the USB directly, code libraries are available which allow the board to emulate a computer keyboard, mouse, and more using the USB-HID protocol!

Description

Leonardo is an Atmega32u4 based microcontroller board. 20 digital I/O pins (7  PWM out, 12  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.

connected to a computer via usb,or 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.
