This 3D Printer MKS OSC Stepper Motor Controller Pulse PWM Speed Reversing Module is a pulse generating module, which used as a  signal for stepper drivers. To control the stepper motor, it must be equipped with the driver. The module can be used as Easy controller + stepper driver + stepper motor + DC power composed a simple control platform.

It consists of 3 kinds of frequency signal, including 5.4k-160khz, 540-16.6khz, 80-2.4khz, which can be chosen. Support generating a pulse and PWM signal, support skipping stitch choice. For frequency measurement there are two ports of PUL and common-cathode (or common anode) can be measured.

Different stepping motor driver different port sign, but same function
