Product Description

Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/Wiring language. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g. Flash, Processing, MaxMSP). The open-source IDE can be downloaded for free (currently for Mac OS X, Windows, and Linux).

The Arduino Mega is a microcontroller board based on theATmega2560. 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.

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.

Arduino Mega 2560 (Revision 3)



The Arduino Mega 2560 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.

The Mega 2560 is an update to the Arduino Mega, which it replaces.

The Mega2560 differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the ATmega16U2 (ATmega8U2 in the revision 1 and revision 2 boards) programmed as a USB-to-serial converter.
Revision 2 of the Mega2560 board has a resistor pulling the 8U2 HWB line to ground, making it easier to put into DFU mode.

Revision 3 of the board has the following new features:
  • 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.

Specifications

    Microcontroller: ATmega2560
    Operating Voltage: 5V
    Input Voltage (recommended): 7-12V
    Input Voltage (limits): 6-20V
    Digital I/O Pins: 54 (of which 14 provide PWM output)
    Analog Input Pins: 16
    DC Current per I/O Pin: 40 mA
    DC Current for 3.3V Pin: 50 mA
    Flash Memory: 256 KB of which 8 KB used by bootloader
    SRAM: 8 KB
    EEPROM: 4 KB
    Clock Speed: 16 MHz

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

There are quite a few differences between the Rev2 and the Rev3 Arduino boards.

1.) The pinout of the Arduino Rev3 boards has been changed by adding SDA and SCL pins near the AREF pin and two more pins (IOREF and NC) near to the Reset pin.

2.) The ATmega8U2 has now been replaced with the ATmega16U2 which is also an 8-bit microcontroller with USB 2.0 Full-Speed Support.

3.) Stronger RESET Circuit.

It also comes with its own beautiful box like the Arduino Uno with a thank you note from the Arduino Team as well as a set of stickers for showcasing on your own DIY project.
