The Arduino Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU. It is the first

Arduino board based on a 32-bit ARM core microcontroller. It has 54 digital input/output pins (of which 12 can be

used as PWM outputs), 12 analog inputs, 4 UARTs (hardware serial ports), a 84 MHz clock, an USB OTG capable

connection, 2 DAC (digital to analog), 2 TWI, a power jack, an SPI header, a JTA G header, a reset button and an

erase button.

The board contains everything needed to support the microcontroller; simply connect it to a computer with a micro-

USB cable or power it with a AC-to-DC adapter or battery to get started. The Due is compatible with all Arduino
