This Mega 2560 development board is 100% compatible with Arduino and is designed for your most ambitious projects which require additional pins and extra memory.
Based on the 8-bit AVR microcontroller ATmega2560, it has 54 digital I/O pins, 16 analog inputs and a larger space for your sketches. 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 2560 board is compatible with most shields designed for the Uno.
The ATmega+2560 comes preprogramed with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. The Mega R3 has a re-settable fuse that protects your computer's USB ports from shorts and over-current. Although most computers provide their own internal protection, the fuse provides an extra layer of protection. If more than 500 MA is applied to the USB port, the fuse will automatically break the connection until the short or overload is removed.
The ATmega+2560 controller board has 256 KB of flash memory for storing code (of which 8 KB is used for the bootloader), 8 KB of Spram and 4 KB of EEPROM (which can be read and written with the Eeprom library).
