Gravity: 130 DC Motor Module

Gravity: 130 DC Motor Module combines a classic 130-size brushed motor with an onboard transistor control circuit, creating a compact actuator solution for rapid prototyping and embedded motion projects. The integrated switching stage allows direct digital control from popular development platforms such as Arduino without requiring a separate motor driver board. A standardized Gravity pin connector simplifies wiring and improves reliability during experimentation. This small DC motor unit supports PWM-based speed control, making the module suitable for robotics mechanisms, airflow experiments, and interactive hardware builds where quick installation and stable power switching are important.
