The 5050 member of the single-wire WL-ICLED family. The package looks like a WS2812B and nothing else about it is the same: the pin order is VSS, DIN, VDD, DOUT going counter-clockwise from the marked corner (the WS2812B’s is VDD, DOUT, VSS, DIN), the supply minimum is 3.5 V, and the PWM frequency is 2.5 kHz. Do not drop it onto a WS2812B footprint.
