Description:

The Arduino Leonardo is a microcontroller board based on the ATmega32U4. It has 20 digital input/output pins (of which 6 can be used as PWM outputs and 12 can be used as analog inputs), a 16 MHz resonator, a USB connection, a 2.5mm center positive barrel jack, an in-circuit serial programming (ICSP) header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a micro USB cable or power it with a AC-to-DC adapter or battery to get started (USB cable and power supply are not included). This board ships with the power jack and through-hole headers soldered in, as shown in the product picture.

The Leonardo differs from all preceding Arduino boards in that the user-programmable ATmega32U4 AVR microcontroller has built-in USB functionality, eliminating the need for a secondary processor. This makes the Leonardo more versatile: in addition to supporting a virtual (CDC) serial/COM port interface, it can appear to a connected computer as a mouse and keyboard. See Arduino’s getting started page for more implications of the Leonardo’s single-MCU design.

The Arduino has a large support community and an extensive set of support libraries and hardware add-on “shields”.

More information about the Arduino Leonardo is available on Arduino’s website. Note that the Leonardo only works with the Arduino IDE version 1.0.1 or later.
