Arduino Due

The first Arduino board based on a 32-bit ARM core microcontroller.  Arduino Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU,  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.

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 shields that work at 3.3V and are compliant with the 1.0 Arduino pinout.

Features:

• Contains everything needed to support the microcontroller

• Power it with a AC-to-DC adapter or battery to get started

• Compatible with all Arduino shields that work at 3.3V

• Arduino board based on a 32-bit ARM core microcontroller

Technical Specs:

• Microcontroller: AT91SAM3X8E • Operating Voltage: 3.3V • Input Voltage (recommended): 7-12V • Input Voltage (limits): 6-20V • Digital I/O Pins: 54 (of which 12 provide PWM output) • Analog Input Pins: 12 • Analog Outputs Pins: 2 (DAC) • Total DC Output Current on all I/O lines: 130 mA • DC Current for 3.3V Pin: 800 mA • DC Current for 5V Pin: 800 mA • Flash Memory: 512 KB all available for the user applications • SRAM: 96 KB (two banks: 64KB and 32KB) • Clock Speed: 84 MHz Warning: Unlike other Arduino boards, the Arduino Due board runs at 3.3V. The maximum voltage that the I/O pins can tolerate is 3.3V. Providing higher voltages, like 5V to an I/O pin could damage the board.
