Don’t limit your projects, think big, think MEGA! The Arduino Mega 2560 has been designed with bigger and more ambitious projects in mind. The large number of analog and digital pins, together with a larger memory makes it ideal for devices like 3D printers and other demanding applications. Backward compatibility with existing shields and sketches is provided, but other shields target the Mega specifically, exploiting the full potential of this board.
The Mega 2560 is a board based on the 8-bit AVR microcontroller ATmega2560 by Atmel. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports). It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable. The Mega 2560 board is compatible with most shields designed for the Uno. To compare this board to the current, past or outdated boards see the Comparison Page.

Arduino Mega 2560 is programmed, as all the other Arduino boards with the Arduino Software (IDE) that you can download for free.
Arduino Uno Rev3 is programmed, as all the other Arduino boards with the Arduino Software (IDE) that you can download for free.
It can get maximum storage capacity with 2 microSDHC or 2 microSD cards. CR-5400 converts 2 microSD(HC) cards into one MS Pro Duo stick. You can get twice the capacity at a lower price. The card types can be mixed too.
This adapter can work with only one microSDHC card as well. The second slot can be equipped anytime later.
