Arduino Due (32-bit ARM Cortex-M3)

The Arduino Due is Arduino’s 32-bit development board built around the ATSAM3X8E ARM Cortex-M3 microcontroller running at 84 MHz. If you’ve outgrown 8-bit boards and want more speed, more memory, and advanced peripherals, the Due is a strong step up for robotics, motion control, and embedded prototyping.

Why Choose Arduino Due?

  • 32-bit ARM Cortex-M3 performance at 84 MHz
  • Large I/O count for complex builds (many sensors, drivers, and peripherals)
  • True analog output via built-in DAC pins (great for audio, control signals, and waveform generation)
  • USB OTG-capable port for host/device projects
  • Ideal for advanced Arduino IDE projects that need more headroom than Uno/Mega

What You Can Build

  • Robotics controller with multiple motor drivers and sensors
  • Data logger with many analog channels
  • CAN-based automotive or industrial prototypes
  • Real-time control systems and motion projects
  • USB HID/OTG experiments and connected devices

Important Note: 3.3V Logic

Unlike many Arduino boards, the Arduino Due uses 3.3V logic. The I/O pins are not 5V tolerant. If you are connecting 5V sensors or modules, use a level shifter to protect the board.

Pinout and Power Notes

  • Use 3.3V sensors/modules whenever possible.
  • For 5V modules, add a logic level shifter on signal lines.
  • The Due follows the Arduino 1.0 pinout; only use shields designed for 3.3V operation.
  • Check the official pinout PDF for exact mappings and special functions.
