The Arduino Due is Arduino's first ARM-based development board, powered by the Atmel SAM3X8E — a 32-bit Cortex-M3 processor running at 84MHz. With 54 digital I/O pins, 12 analogue inputs, 2 DAC outputs, and USB-OTG, it brings significantly more computing power while remaining programmable through the familiar Arduino IDE.
The Due supports features not available on 8-bit Arduino boards, including true analogue output (DAC), DMA, and an experimental multitasking library. It uses the Arduino R3 layout, making it compatible with shields that fully implement this standard.
