The outer diameter is almost 86mm, and the inner diameter is 72mm (the pcb is 7mm thick, 7+7+72 = 86). Not 85 and 70 as stated in the description. Not a big problem for me, but I was glad that I foresaw that the diameter could be wrong when I designed my thingy :) It seems to be standard WS2812B 5050 RGB, it says WS281B on the PCB but it seems to be a misprint. It works perfectly when I tested with an old program for WS2812B.
