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 support Mac OS X, Windows, and Linux).

The Arduino Mega is a microcontroller board based on the ATmega2560. 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.

* It does not come with USB B Cable, please get it seperately at the bottom of this page.

This is the new Arduino Mega 2560 which replaces previous Arduino Mega. In addition to all the features of the previous board, the Mega 2560 now uses an ATmega8U2 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.

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.

Q & A (9)
What is the size of the DC jack female end on the board? is it 5.5*2.1mm? ( Naveen , 27/10/2022 )
Hi, yes the size is 5.5*2.1mm.
does the arduino mega have a plastic casing to hold the main chip ( Naveen, 28/09/2022 )
Hi, the board comes with the plastic base as shown in the product photo.
Is this actually running 8U2 or 16U2? A little bit confused. ( Goh Pei Fung , 11/01/2020 )
Hi, it is 16U2 as stated on the product page. Thanks :)
Hi, when will this board be available in stock again? Thank you :) ( Daniel, 15/01/2019 )
Hi, this item will available in 4-5weeks. Please click on notify me button and we will send you an email notification once we have stock :)
hi, may i know when will this board be available for purchase? ( bryan chuah, 09/10/2017 )
Hi, it will be available in 2-3 week. Thanks :)
Do you have any warranty for the board? if yes, to whom should i refer to? ( roslina, 27/09/2017 )
Hi, you can fill up this form and our FAQs for more info on warranty. Thanks :)
Hi, does this item still available? ( Firdaus, 30/05/2017 )
Hi, yes it is available. Thanks.
Is this original from Arduino or just a replica board from 3rd party? Tq ( jeff, 14/09/2015 )
Hi, This is original board from Italy. Thanks.
For this arduino can it communicate back to PC or send signal back to PC? I need it to send signal back to PC so that I can send a SMS to hand phone from PC. ( Tan Min Chin, 05/03/2015 )
Sure you can, there is a USB to UART chip on this Arduino and it is bi-directional communication. It appears as COM port on computer. If you have further inquiry, please do discuss in our technical forum as this section is for short inquiry, thanks :)
