Arduino Due R3 — High‑Performance 32‑bit Development Board for Advanced Projects

The Arduino Due R3 is a powerful 32‑bit microcontroller platform built around the ARM Cortex‑M3 core, designed for demanding embedded systems, real‑time control, and advanced prototyping. With its high clock speed, rich I/O, and native USB‑OTG support, it’s ideal for both electronics engineers and hobbyists integrating electronics components, sensor modules, and complex peripherals. Whether you’re building with Arduino or bridging to a Raspberry Pi, the Due R3 delivers the performance and flexibility your project needs.

🔧 Key Features

• 32‑bit ARM Cortex‑M3 processing: AT91SAM3X8E delivers a major step up in performance over 8‑bit boards for compute‑intensive tasks.
• Rich I/O connectivity: 54 digital I/O (12 PWM), 12 analog inputs, and 2 true DAC outputs for precise analog signal generation.
• USB‑OTG host/device: Native USB On‑The‑Go enables the board to act as a USB host or device for flexible connectivity to USB peripherals.
• High clock frequency: 84 MHz system clock for fast instruction execution and responsive real‑time control.
• 3.3V logic with wide input range: Operates at 3.3V logic; recommended input voltage 7–12V for stable regulation.
• Generous memory: 512 KB Flash and 96 KB SRAM to support complex firmware, buffers, and data processing.
• Arduino ecosystem: Compatible with the Arduino IDE, libraries, and many 3.3V shields—ideal for rapid prototyping with common electronics modules.
