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.
