Arduino leonardo board..

        The Arduino Leonardo is a microcontroller board based on the ATmega32u4. It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button.

• What is the Arduino Leonardo used for?

    The Leonardo board uses a single microcontroller to run your sketches as well as communicate with your PC using USB. This allows Leonardo far more flexibility in its communication with the computer. It also helps to lower the cost of the board.
