The Arduino Due is a microcontroller board based on the Atmel SAM3X8E CPU, which is the first one based on 32-bit ARM core arduino. 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.

Note: This is not the same as 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.

The biggest change of Due is that it works with a voltage of 3.3V.
The IO port can carry the voltage to 3.3V. So it is not compatible with the original 5V design for the Shield and peripherals.
Inappropriate connection to the 5V power supply and peripherals may burn DUE Iduino, please check the voltage before use.

ARM core strengths
The use of 32 bit ARM core Due compared to the previous use of the other Iduino core 8 AVR more powerful.
The main differences are:
32 bits at a clock can process 32 bits of data.
CPU clock frequency of 84Mhz
96 SRAM KBytes
512 Flash KBytes
A DMA controller, can reduce the pressure on the CPU to do a lot of computing
