Original Arduino Mega 2560 R3
Arduino Mega 2560 Rev3 is a microcontroller board based on ATmega2560 (datasheet). It has 54 digital input/output pins (14 of which 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.< /DIV>
Contains everything needed to support the microcontroller; Connect it to a computer with a USB cable or power it with an AC-DC adapter or battery to get started. Mega is compatible with most shields designed for Arduino Duemilanove or Diecimila.
