Yet another WS2812 wifi controller.
The idea was to make a small PCB that could be soldered onto the end of a LED strip.
The integrated DC-DC buck converter allows to power the strip with a higher voltage, allowing thinner and longer wires.

Did you tested how much lag it applies? Do you use TCP or UDP?

  Are you sure? yes | no

Nope, I didn't bother with that. I'm using it over MQTT with Home Assistant.
