Compatibility & Use Cases 🔌

Ideal for Arduino and Raspberry Pi projects using a suitable motor driver module. Perfect for PWM speed control experiments, airflow measurement, basic propulsion demos, and small vehicles. Integrates well with common electronics modules and breadboards.

Integration Tips for Microcontroller Projects 🧠

• Switch the motor with an NPN transistor/MOSFET or a motor driver IC (e.g., L293D, TB6612FNG); do not drive directly from a microcontroller pin.
• Add a flyback diode across the motor terminals to protect your electronics.
• Power the motor from a separate 1.5–3 V rail or AA battery pack; connect grounds in common with your control board.
• Use PWM for speed control via Arduino or Raspberry Pi (through the driver stage).

Notes & Safety ⚠️

• High RPM propeller—keep fingers, hair, and loose clothing clear during operation.
• At 3 V, speed and current increase significantly; ensure your driver can supply the required current.
• Observe correct polarity. Reversing polarity will reverse rotation direction.
