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!
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.
Frequently Asked Questions:
- Are these 100% compatible with the "normal" Arduino's?
Yes, they really are 100% completely compatible with "normal" Arduino's. Build quality looks the same and everything (studio, library, tools, etc) just works. You may read the reviews.
- What if I'm still concerned about this being named as "Arduino Compatible"?
If still in doubt, please buy from Arduino's official dealer channels. Yes they are more expensive. We use these internally ourselves for various electronic projects and find them to be 100% decent (again, check reviews). That said, we do not make these and we are providing all the information we know.
