Excellent and informative video, thanks! Not sure if you have seen it, but Martyn Davies has also done a great video showing how to control it through software on an Arduino, too....so this can be a very useful module.

Will the set frequency and duty cycle for both channels individually remain the same even after the power supply is removed? or it gets reset once the power supply is removed.

Hi! Great explanation. I have a 5-55V PWM speed controller that is used for controlling a DC motor 12VDC, and I want to use a e-bike throttle with it. From the PWM controller, there is a control input for 5V, Ground, and Signal (Red, Black, & Yellow) and on the e-bike throttle there is the same 3 wires for throttle control. When hooked to the PWM Controller with the e-bike throttle currently, the motors turn slightly and there is .9VDC measured between the signal wire and the ground wire of the control wiring. I think this is because the e-bike throttle uses a hall sensor and operates on 1-4V control signal while the PWM was originally using a 100K ohm potentiometer that is looking for 0-5V. I am not worried about the top end of the voltage, just want to stop the motors from turning automatically and need to use the e-bike throttle. Can you help with this?

I just got some of these modules with the same model number on the back, and they're junk because the LCD is basically illegible. They're essentially blank from straight on, and only at extreme angles do you get any usable contrast at all. I have a previous batch that also sucks from straight on, but if you look up at it from about 45 degrees below, the digits are clear. Obviously that's still useless if the display is mounted in something. Generally these seem to suck. There are LED ones, but they have only one display for all functions and it's not clear how they indicate what you're adjusting or what the default display is.
