Feature

1.0 pinout: added SDA and SCL pins that are 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. In future, shields will be compatible both with the board that use
the AVR, which operate with 5V and with the Due that operate with 3.3V. The second one
is a not connected pin, that is reserved for future purposes.

Description

The Mega 2560 is a microcontroller board based on the CH340. It has 54 digital input/output pins
(of which 15 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 Duemilanove or Diecimila.
The Mega 2560 is an update to the Mega, which it replaces.
The Mega2560 differs from all preceding boards in that it does not use the FTDI USB-to-serial
driver chip. Instead, it features the CH340 programmed as a USB-to-serial converter.
Revision 2 of the Mega2560 board has a resistor pulling the 8U2 HWB line to ground, making
it easier to put into DFU mode.
Revision 3 of the board has the following new Features:
1.0 pinout: added SDA and SCL pins that are 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. In future, shields will be compatible both with the board that use
the AVR, which operate with 5V and with the Due that operate with 3.3V. The second one
is a not connected pin, that is reserved for future purposes.
