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, a power jack, an SPI header, a JTAG header, a reset button and an erase button.

        
      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.
