I want to know what variant this RGB strip belongs to. As I have to order this exact rgb strip directly from AliExpress to extend my setup.
If it is, WS2812B/WS2812/WS2811/SK6812/UCS1903/WS2801

I closely suspect this strip might correspond to type "WS2811" but the main distinguishing feature is about the bus lines architecture:

The one on my strip is:

====+12V====
====GND====
====D In====/ D Out


But for all the variants I found on AliExpress it is:

====+12V====
====D In====/ D Out
====GND====

** The only thing I'm sure is about the chip used which is SMD 5050 which exactly corresponds to the chips installed on my strip.

Request modders here to help me find the exact RGB strip variant which will help me expand my led setup.
