How To Use:
The module has 8 independent buttons to set the frequency and duty cycle. It supports short press (increase or decrease by one unit) and long press (rapid increase or decrease). It is very simple. After setting the parameters, it will be automatically saved and not lost after power?off.
The 3?channel duty cycle buttons can be pressed at the same time to adjust in real time. The LCD shows the percentage of the button pressed later, which is very real?time and can be used as a simple duty cycle scan of several channels.
