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 Uno, Duemilanove or Diecimila.

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

Additional features coming with the R3 version are:

  • ATmega16U2 instead 8U2 as USB-to-Serial converter.
  • 1.0 pinout: added SDA and SCL pins for TWI communication placed 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 and the second one is a not connected pin, that is reserved for future purposes.
  • stronger RESET circuit.

A great bit of kit - worked straight out of the box. 10 minutes later it was running a test program (supplied with the IDE). Programming is straightforward and the forum people at are friendly and helpful when you need advice.As an ex-IT lectu

High Quality - Official Boards
Thursday, 6 December 2012  |  Russell

I've bought a few boards for projects, normally the Chinese clones. But this board is official, High Quality, and I got it next day. I recommend proto-pic to anyone.
