The Arduino Due is the first Arduino board based on a 32-bit ARM core microcontroller. With 54 digital input/output pins, 12 analog inputs, 2 DAC and 2 CAN it is the perfect board for powerful larger scale Arduino projects.

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 JTAG header, a reset button and an erase button.
Atmel SAM3X8E ARM Cortex-M3 CPU

Based on the ARM® Cortex®-M3 processor, this 32-bit microcontroller has 84 MHz clock and 96kb of SRAM.

54 digital pins

The Due has 54 digital pins, 12 of which support PWM (Pulse Width Modulation).

Analog pins

The Due has 12 analog input pins, and 2 DAC pins.

Battery Connector

The Arduino Due features a barrel plug connector, that works great with a standard 9V battery.

CAN support

The Due comes with two CAN (Controller Area Network) buses.

All you need to know to get started with your new Arduino board.

Suggested Libraries

The USBHost library allows an Arduino Due board to appear as a USB host, enabling it to communicate with peripherals like USB mice and keyboards.
The Servo library allows an Arduino board to control RC (hobby) servo motors.
This library allows you to communicate with I2C / TWI devices.
