Flickering in LED WLED set up

Questions
1

Hi guys,

Could you please help me out with this one?

I’ve got the following set up.

A light box of 90x200cm with in total 11,4 meters Pautix 24V Cob Rgbic Pixel.

  • 24V 5a power supply
  • DC-DC converter 12-24V to 5V 3A
  • ESP32 WROOM
  • WLED sound reactive (latest version)
    All inside the lightbox next to the first LED strip.

When i turn on the lights it’s all steady but when i start using WLED the LEDS start flickering.

I’d try putting a resistor between the data line but it didn’t help.

Thanks in advance.

If you haven’t got a levelshifter yet, get one of the KB recommended ones: Levelshifters

Make sure you wire it up properly, no floating inputs and a 100nF ceramic bypass capacitor.
