YF-18 Stepper Motor Speed Controller with Digital Display 8-24V DC

 

It is a pulse-generating module used as a signal for stepper drivers. This simple and easy to use stepper motor speed controller has stable performance. The speed controller has the function of memorizing the last set speed value after power off.

 

It needs to be used with a driver to control the stepper motor; In other words, you need the following components as a minimum: a controller (like Arduino), you also need a stepper driver (like TB6600, TB6560) and of course the stepper motor.
