Arduino MEGA 2560 R3 + USB Cable

MEGA 2560 R3 ATmega2560 AVR USB board USB cable (ATMEGA2560 /atmega16u2 ) 2560

This is the new Mega 2560. In addition to all the features of the previous board, the Mega 2560 now uses an ATmega16U2 instead of the FTDI chip. This allows for faster transfer rates, no drivers needed for Linux or Mac (inf file for Windows is needed), and the ability to have the board show up as a keyboard, mouse, joystick, etc. It also has twice as much flash memory.

This is the new R3 version of the Mega 2560 with the following changes

• 1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board. In future, shields will be compatible both with the board that use the AVR, which operate with 5V and with the Arduino Due that operate with 3.3V. The second one is a not connected pin, that is reserved for future purposes.
• Stronger RESET circuit.
• Atmega 16U2 replace the 8U2.

Mega Profile:

The Mega 2560 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 Arduino Mega is compatible with most shields designed for the Arduino Duemilanove or Diecimila.
