Arduino-Compatible DUE R3 Board SAM3X8E 32-bit ARM Cortex-M3

Product is discontinued.

Product Description

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.

The Arduino Due is programmed using the Arduino Software (IDE), our Integrated Development Environment common to all our boards and running both online and offline. For more information on how to get started with the Arduino Software visit the Getting Started page.


We purchased this version of the Arduino Due from a source in China in the hope for a good deal. The only reason that the board did not pass our quality control lies in the fact that the user needs to download and install a driver (Windows, Linux, Mac), meaning the board is not automatically detected by the Arduino IDE. Also, the COM port assigned to the Due is displayed as a regular port, not as an Arduino port. Otherwise, the board is fully Arduino Due compatible. An experienced user should have no problems using the board.

We are selling the board under purchasing price to free up inventory space. Shipping within the United States is free.


  • Microcontroller: AT91SAM3X8EA 
  • Operating voltage: 3.3V 
  • Input voltage(recommended): 7V - 12V 
  • Input voltage(limits): 6V - 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: 130mA 
  • DC current for 3.3V pin: 800mA 
  • DC current for 5V pin: 800mA 
  • Flash memory: 512KB all available for the user applications 
  • SRAM: 96KB (two banks: 64KB and 32KB) 
  • Clock speed: 84MHz 


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. 

Package includes: 

  • 1 x Arduino compatible DUE R3 
  • 1 x USB cable
