Leonardo R3 Board Micro-USB compatible with Arduino

Description

The Leonardo R3 Board Micro-USB compatible with Arduino 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.

The Leonardo R3 Board differs from other boards by using a separate USB-Serial chip in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started.

This R3 Board Micro-USB allows the Leonardo 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.

• This allows Leonardo to appear on a connected computer as a mouse and keyboard.
• It is FCC and CE certified which are made of environmentally friendly materials and production technology, made of function, voltage, and current before packing
• The Arduino Leonardo appears to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial COM port.
• R3 board is small and easy to operate. It has Atmega 32u4 microcontroller and USB enabled.
