Frequently Asked Questions
Yes, it has a built-in reduction gearbox designed to maximize output torque while regulating speed.
It is compatible with standard motor driver modules such as the L298N, TB6612FNG, or generic stepper drivers depending on the exact coil wiring.
No, motors draw significant current and should always be powered via an external battery pack or power supply, with only control signals coming from the microcontroller.
