You could use it. But this will drive LED dim and bright using voltage. The best way to increase and decrease the intensity of LED light is PWM so you will have fixed for example 5V (voltage will not change) but PWM will change from 0% (dim) to 100%( bright).

Hi, I can see that all 3 GND pins are interconnected (on the backside of the module). This way, the GND from PWM source is connected to GND from DC 12-30V source. Is it okay? Does the module have any protection against overvoltage from DC source to PWM ground in case of DC source failure?

Hi, I want to use this module in an application where the pwm frequency is 10 Hz!! The module is designed for 1kHz upt to 3kHz. So, if I would use it in my application, the voltage ripple would become very high. Is there a schematics available? Or can you tell me which resistor and capacitor are responsible for the output filtering/time constant, so that I can change them?

@robojax 5 жыл бұрын

this module uses LM358 OpAMP www.ti.com/lit/ds/symlink/lm358.pdf and quick google search for "LM358 PWM" resulted to many pages. Here is one which I traced from "google images" henrysbench.capnfatz.com/henrys-bench/arduino-projects-tips-and-more/arduino-lm358-op-amp-pwm-to-voltage-converter/ you might be able to change it if you know what you are doing.

@86jogger 5 жыл бұрын

Robojax Thanks for your reply! I think the LM358 is not the "problem", because it is a standard OpAmp. It becomes a Low pass filter by the used resistors and capacitors in the schematics. The problem is that I can't figure out the resistor and capacitor which are responsible for the low pass filter because it is not so easy to figure out the schematics of this by having a look on a picture of the circuit board.

Do you think there is a way for this converter to work in reverse for that application? Currently it works when hooked up, but motors turn slightly due to the hall sensor throttle giving the controller a different control voltage signal than what it needs. Other than turning slightly everything else operates normally, just need to knock out that 1v signal that the hall sensor is giving out while still being able to vary the voltage with that throttle.
