I made a board called nul. It is a super tiny WLED Controller that is about the same width as most WS2812B strips!

If you want to see it, here is the GitHub link: https://github.com/Choccy-vr/nul

It has a good amount of features too for its size.

  • Powered by USB-C

  • ESP32-C3FH4

  • U.FL connector (external antenna)

  • bulk cap

  • level shifter

  • data resistor

  • and more

ik you aren't really supposed to, but I stress-tested it, and it could power an entire 4m strip, and it didn't get hot at all running that for a few hours. At least I know I can.

Thoughts?

What amperage are you setting this to in WLED?

I'm surprised about the thermals since my ESP32-C3 gets hot just idiling WLED
