Frequently asked questions
How do I control the direction and speed of this motor?
Use a motor driver with H-bridge outputs, such as an L298N-type module, powered from 12 V. Reverse the polarity through the driver to change direction, and use PWM on the enable input to control speed.
What power supply should I use for it?
Use a 12 V DC supply that can deliver the motor's current under load, with a margin for the motor driver. Do not run the motor above its rated 12 V.
