Arduino ATmega1280


Arduino ATmega1280-16AU USB board + USB cable


The Mega is a microcontroller board based on the ATmega1280. It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4UARTs(hardware serial ports), a 16MHzcrystal 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 Duemilanove or Diecimila.
