The Mega 2560 is a microcontroller board based on
. 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 2560 board is compatible with
most shields designed for the Uno and the former
boards Duemilanove or Diecimila.
The Mega 2560 is an update to the Arduino Mega
