Mega 2560 R3 Mega2560 REV3 ATmega2560-16AU Board + USB Cable

The Mega 2560 is an update for the Arduino Mega, which it replaces.The board is a microcontroller board based on the ATmega2560-16AU. 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.
