The Arduino Due is an integrated microcontroller circuit that uses the Atmel SAM3X8E ARM Cortex-M3 CPU. It was the first Arduino board to use a 32-bit ARM core microcontroller. It has 54 digital inputs / outputs (12 of which have PWM output pins), 12 analog inputs, 4 UARTs (serial hardware), 84 MHz clock, USB OTG 2 DAC (digital, analog), 2 TWI, one power jack, one SPI header, one JTAG header, one reset button and delete button.

The integrated circuit contains everything needed to support the microcontroller; Just connect it to your computer with a micro-USB cable or with an AC-to-DC adapter or use the battery as a power source.

Note when using the Arduino Due board

There is no point unlike other Arduino boards, it only runs at 3.3V. The highest voltage input on the I / O pins that can withstand is 3.3V if higher can burn and destroy the board.


Advantages of Arduino Due

The control board runs on a 32-bit ARM core, so it works better than conventional 8-bit controllers. Specific differences are as follows:

32bit ARM core.
The CPU runs at 84MHz.
96 Kbytes SRAM.
512Kbytes of Flash memory.
Internal DMA controller supports CPU.
