ARDUINO DUE CLONE
The Due is Arduino's first ARM-based development board.
Based on a powerful 32bit CortexM3 ARM microcontroller made programmable through the 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.
Other features like DACs, Audio, DMA , an experimental multi tasking library. 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)
BEWARE! 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. 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.

Arduino Due (Arm Core) benefits over other Arduinos
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.
