Arduino Mega 2560 Rev3

The Arduino Mega is the big brother of the Arduino Uno. It has 54 digital I/O pins in which you can attach a lot of sensors, drivers, and other modules. It also has 16 analog inputs and 4 UART, the hardware serials. The oscillator clocks at 16 MHz. The USB is a B-Type which the conventional USB for most printers also.

Many changes have been implemented for the R3 version, to name a few: 

It has ATmega16U2 instead of 8U2 as the USB-to-Serial converter.
1.0 pinout: added SDA and SCL pins for TWI communication placed near the AREF pin and two other new pins placed near the RESET pin, the IOREF that allows the shields to adapt to the voltage provided from the board and the second one is a not connected pin, reserved for future purposes
Improved RESET circuit.
