ARDUINO
MEGA 2560 REV3
Overview
The Arduino Mega 2560 is an ATmega2560-based
microcontroller board. It has 54 digital I / O pins (15 can be used as PWM
outputs), 16 analog inputs, 4 UART ports, 16 MHz crystal oscillator, USB port,
power socket, ICSP head and reset button. It contains everything needed to
support the microcontroller. Just connect it to a computer with a USB cable or
plug it into a power adapter or battery to get started. The Mega 2560 is
compatible with most shields designed for the Uno and the former boards
