Arduino Mega 2560

The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. The Mega is

compatible with most shields designed for the Arduino Duemilanove or Diecimila. 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
