Overview

The Iteaduino DUE is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 core. It is the improvement board based on the Arduino DUE. It has 54 digital IO pins, 12 analog inputs, 4 UARTs, an 84MHz clock, a USB OTG capable connection, 2 DACs, 2 IIC, a power jack, a SPI header, a reset button and an erase button.

 

Warning: Unlike other Iteadduino boards, the Iteaduino 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.

 

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

The Due follows the 1.0 pinout:

  • TWI: SDA and SCL pins that are near to the AREF pin.
  • The IOREF pin which allows an attached shield with the proper configuration to adapt to the voltage provided by the board. This enables shield compatibility with a 3.3V board like the Due and AVR-based boards which operate at 5V. An unconnected pin, reserved for future use.

ARM Core benefits

  • The Due has a 32-bit ARM core that can outperform typical 8-bit microcontroller boards. The most significant differences are:
  • A 32-bit core, that allows operations on 4 bytes wide data within a single CPU clock.
  • CPU Clock at 84Mhz.
  • 96 KBytes of SRAM.
  • 512 KBytes of Flash memory for code.
  • A DMA controller, that can relieve the CPU from doing memory intensive tasks.
  • Features:

  • Microcontroller: AT91SAM3X8E
  • Operating Voltage: 3.3V
  • Recommended Input Voltage: 7-12V
  • Min-Max Input Voltage: 6-20V
  • Digital I/O Pins: 54 (of which 12 provide PWM output)
  • Analog Input Pins: 12
  • Analog Outputs Pins: 2
  • 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

Quite OK Review by Jaroslaw
I use it together with originbal Arduino boards.
I have noticed only one difference - ressetting the board while opening programming port does not work.
I have traced it to wrong resistor value ( assembly issue) - 10k in series does not pull down reliably NTRSTB which has internal 15k pull-up. This requires rework, a bit nasty ( 0402 resistor) - 10k -> 1k (Posted on 4/26/2014)
