This controller has the same original function, but has the function of generating PWM signal. There is a jumper on the board, which can be set and selected. The default setting is to generate pulse frequency signal.

REQ is to generate pulse frequency signal

PWM is to generate PWM signal

Product description:

1. This module is a pulse generation module, which supplies the stepper driver as a signal. If you want to control the stepper motor, you must also match the driver.
2. This simple controller + stepper driver + stepper motor + DC power supply can form a simple control platform. Now the controller has 3 frequency signals of high, medium and low, which can be selected by jumper.

The frequency parameters are approximately:

High: 5.8KHZ-127KHZ

Medium: 590HZ-15.8KHZ

Low: 82HZ-2.3KHZ
