The Arduino Mega 2560, the successor to the Arduino Mega, is a microcontroller board based on a ATmega2560 AVR microcontroller. It has 70 digital input/output pins (of which 14 can be used as PWM outputs and 16 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 USB cable or power it with a AC-to-DC adapter or battery to get started.

The Mega 2560 differs from the preceding Mega in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega8U2 programmed as a USB-to-serial converter. This auxiliary microcontroller has its own USB bootloader, which allows advanced users to reprogram it.

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

The Arduino Mega revision R3 adds SDA and SCL pins next to the AREF. In addition, there are two new pins placed near the RESET pin. One is the IOREF that is meant to allow shields to adapt to the voltage provided from the board. The other is a not connected and is reserved for future purposes. The Mega 2560 R3 works with all existing shields but can work with new shields that use these additional pins.
