Description: The Due is Arduino’s first ARM-based Arduino development board. This board is based on a powerful 32bit CortexM3 ARM microcontroller made programmable through the familiar Arduino IDE. It increases the computing power available to Arduino users keeping the language as compatible as possible so that many programs will be migrated in a matter of minutes!
The Arduino Due has 54 digital input/output pins (of which 12 can be used as PWM outputs), 12 analog inputs, 4 UARTs (hardware serial ports), an 84 MHz clock, a 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. There are also some cool features like DACs, Audio, DMA , an experimental multi tasking library and more.
To compile code for the ARM processor, you’ll need the latest version of the Arduino IDE: v1.5 (After a period of testing and debugging this will replace the 1.0.1 IDE altogether)
Because of the limitations of system voltage imposed by the Atmel SAM3X8E, Arduino shields that are based on the 5v models won’t work properly. All the shields that fully implement the Arduino R3 layout are compatible straight away (like the Arduino WiFi shield and Ethernet Shield) but other shields might not be compatible. Be careful when you’re plugging stuff in!
Note: 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.

I’ve got real time multitimbral polyphonic DDS working on this bad boy with both DACs outputting composite waveforms! I love this beast!

After initial frustrations with installing the appropriate drivers and configuring appropriate ports, this board has been seamless transition from Arduino UNO.
Arduino Due forums are a great place to get advise if you are experiencing programming issues.

These work great! Same familiar Arduino environment, but a whole ‘nother world in terms of processor performance. Compared to regular Arduino it is blazingly fast and has huge memory. We use it to run a pretty demanding real-time motion control project.
Watch out for those 3.3v i/o’s though. :-)

Great microcontroller. Has one hardware bug that can be annoying, but overall I am impressed.
However, I bought it initially for video processing, trying to merge video and some basic sensors as a home DIY experiment. Unfortunately, I must say that it is still too underpowered for video feeds. BUT!!!! It is an amazing improvement for a bunch of sensor applications, which I must say now work so much more better and I can do so much more with the DUE. One thing I am glad is, that it responds so much faster than the UNO when controlling servos, if I have more sensors connected to it… Be very careful as this board works with 3.3V… some inputs work at 5V so you might turn a very expensive board into confetti…
I purchased this board because the documentation states that you can set the input and output resolution to 12 bits. I needed this for PWM output. Once the output resolution is set to 12 bits you can count up to 4095 but the PWM signal only changes every 16 counts.
The board arrived in working order and I ran a blink test, to ensure that the compile and upload functions were working. What I did have to work at was finding a version of the IDE which would recognize the Due in the Boards Manager. It turned out that version 1.5 was Ok because apparently the Due board definition was incorporated into the IDE definitions. Versions 1.62 and 1.63 however, gave me continuous errors every time I launched the Boards Manager (unable to connect to the internet). Finally I found that version 1.6.5-r2 works with the board manager and with this IDE I was finally able to load the Due Board and work with it. I hope to use the fast ADC’s and large SRAM to record geophone data.

NOT WORKING AT ALL !!
Hi, The Due isn’t like other Arduinos. There are a couple things that you need to know when using this compared to other Arduinos. Make sure to read this over completely, http://arduino.cc/en/Guide/ArduinoDue If you are still having issues or the item is nonfunctional, contact us at https://www.sparkfun.com/returns
