Data Sheet
Overview
The Arduino Mega 2560 is a microcontroller board based on the ATmega2560 (datasheet).
It has 54 digital input/output pins (of which 14 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 Arduino Duemilanove or Diecimila.
