Product Overview: The Leonardo R3 Board Compatible with Arduino is a microcontroller board based on the ATmega32u4 (datasheet). 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. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Leonardo R3 Board differs from all preceding boards in that the ATmega32u4 has built-in USB communication there by eliminating the need for a secondary processor for the USB, this allows the Leonardo R3 Board to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port. It also has other implications for the behavior of the board, these are detailed on the Getting started with the Arduino Leonardo. Getting started: Find inspiration for your projects with Leonardo board from our tutorial platform Project Hub. The Getting started with the Arduino Leonardopage contains all the information you need to configure your board, use the Arduino Software (IDE), and start tinkering with coding and electronics.
