WS2815 and 12volt

[Tarecco]

Hi,

im new here and very desperate, I’m trying to connect my BTF lighting WS2815 with meanwell PS 12V 12.5amp but the leds not turning on. I tried a different PS with 50amp and still the same no light. also I used a second 2815, same result. What I’m doing wrong?

thanks

Welcome! What controller are you using to run the pixels?

Have you got a photo of what you are trying to do so we can see how you've wired everything?

 

[Tarecco]

This my controller, ESP32. Let me know if you need more pictures or information. Thank you

Welcome! What controller are you using to run the pixels?ESP32. It’s WiFi connected.

Seems you're coming directly from the GPIO pin from an ESP, and by assumption assume you are using WLED?
Have you configured the controller outputs to the correct GPIO pins, and confirmed you have the correct GPIO pin on the board connected to the LEDs?
You may require a level shifter, leds need 5v data signals not 3.3v which is what the GPIO pins put out.

Edit: I also see you are using a solderless connector, ditch that and solder the wires in, those things are horrible for connections and give numerous problems (such as what you are seeing now)

Edit 2: Is that breakout board for your ESP rated for 12v input on the terminals you've connected to? Usually they are 5v and 3.3v input and have a special input for 12v sources.

Correct, I’m using WLED controller, I’m using GPIO4 and changed on the controller too. LED needs 12V and not 5V and they don’t need level shifter according to BTF.

All addressable LED's require a 5 volt data signal, 3.3v is not enough in a lot of cases.

ok, can you let me know what I need to do? I mean in details please. Or maybe a draw! Thanks

The quickest way to explain it, would be a link. https://kno.wled.ge/basics/compatible-hardware/#levelshifters This is from the WLED website.

@Tarecco another contributing factor may be that the ESP32 is 5V powered not 12V. Perhaps try powering it via a USB wall charger instead of the 12V supply.

I have done that and I have just used a new controller out of the box.. changed some settings, still no light or any life on the lights.

lol my brain is fried right now.

Are you connecting the Data to the GPIO and the Ground to the ESP, as well as the +12V and Ground to the external power supply? It's imperative that both grounds are connected.

I’m following that tutorial but I don’t see any level shifter. Can anyone explain. Thanks
