🔌 Power and Control Tips

• Use 1–2 AA batteries for standalone operation, or a regulated 1.5–3 V supply with adequate current.
• When controlling via Arduino or Raspberry Pi, drive the motor through a motor driver module (e.g., L293D, L298N, TB6612FNG). Do not power the motor directly from microcontroller pins.
• Reverse polarity to change rotation direction. Consider a driver with PWM for speed control.
• Provide a separate motor supply and common ground with your microcontroller to reduce noise on logic rails.

🔬 Applications

• STEM labs and aerodynamics demonstrations
• Cooling fans for enclosures and electronics modules
• Mini RC prototypes and robotics
• DIY wind tunnel and airflow measurement setups

Engineers and makers will appreciate the straightforward integration with common electronics components and modules, robust propeller material, and reliable high‑speed performance at low voltage. This compact set is a versatile add‑on for any Arduino or Raspberry Pi toolkit.
