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 512KB of flash, 96KB of SRAM, 12-bit ADC/DAC, USB host capability, and CAN bus support, it's the go-to board for projects that demand serious computing power.

The Due excels at audio applications, signal processing, and data acquisition thanks to its 12-bit analogue inputs and dual DAC outputs. The USB 2.0 host interface lets you connect peripherals like mice, keyboards, cameras, and mobile phones directly. It also supports the Android ADK protocol.
