The long awaited ARM board by Arduino is finally here, now you can access higher level functionality while still using the wildly popular Arduino IDE.
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.
If you are looking to interface 5V based product to the due we recommend using the Adafruit 8 channel bi-directional level converter.
The Arduino Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU (datasheet). It is the first Arduino board based on a 32-bit ARM core microcontroller. 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, CAN bus, a power jack, an SPI header, a JTAG header, a reset button and an erase button. If you're curious to what the erase button does well it.....hmmm....how can we put this?....it swiftly eliminates the sketch you've uploaded to it....and in other terms: it erases your sketch.
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 Arduino shields that work at 3.3V and are compliant with the 1.0 Arduino pinout.
Some interesting applications for the Due:

The Due follows the 1.0 pinout:
The Due has a dedicated forum for discussing the board. Here is the specification page for more info.
Note: You will have download the newer Arduino 1.5 and above in order to have the Due board available in the IDE. If you do any work with the ATtiny cores you will have to temporarily remove the "hardware" folder from your main Arduino Sketch folder or the Arduino 1.5.1 IDE will crash on boot. Since we work with the SB-FireFly all the time, this happened to us.
