Parameter Setting Introduction
Short Press The Potentiometer: Select the parameter to be set. Including the duty cycle lower limit, upper limit and output frequency, you can switch by yourself.
The lower limit of the duty cycle is displayed as "L" + two digits; the upper limit of the duty cycle is displayed as "H" + two digits or "100"; and the operating frequency is displayed as "F" + two digits.
Long Press The Potentiometer: Save the parameters and exit the setting mode to the normal display mode.
Rotate The Potentiometer Clockwise: Increase the setting value.
Rotate The Potentiometer Counterclockwise: Decrease the setting value.
STOP Port On The Back: If the user needs other buttons or the control output of the controller, it is used to connect to an external switch button to turn on/off the output.

Kindly Reminder
This module is a PMW driver, which can control the controlled device by changing the frequency and duty cycle of the output signal. It is not a voltage converter, and it has no function to change the output voltage.
