The Arduino Mega 2560 R3 is a microcontroller board based on the ATmega2560 (datasheet). It has 54 digital input/output pins (of which 14 can be used as PWM outputs),16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a 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 Mega is compatible with most shields designed for the Arduino Duemilanove or Diecimila.

What's new with the R3 version of the Mega 2560?  R3 also 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 allow the 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 adapt to new shields which use these additional pins.
