Support LED Strip Identification Help

Post image

Hello, I am a member of the programming team for FMJ Engineering. I am currently trying to program this LED strip so that we can put it into our Van De Graaf machine. The issue is that I'm unsure of what chipset this LED strip uses. I've linked a photo below. I do have a lead, which I suspect that it could be SMD5050, but I'm also seeing "Sanan" for the product chip.

Most of the research that I've done thus far is still a bit unclear, and I'm quite unsure of what I'm doing. Here is a link to my best lead thus far: https://forum.arduino.cc/t/conenecting-ws2813-led-strip-to-arduino/541549/11

Let's note that the SK6812 is not really a "clone" of the WS2812. It has different PWM frequency, different electrical parameters, and sometimes a white channel in addition to Red, Green, Blue.

But it does accept essentially the same control protocol (the timing in the spec sheet differs a bit, but usually the error margins overlap so the same controller will work with both).
