WS2812 RGB SMD-LED "Pixel"

Hey there!

I saw these the other day:

Does someone know more about the size dimensions of the little boards on which the LEDs are soldered to? Usually you get all the informations(*) you want but I really couldn’t find anything about the real size dimensions, except for the dimensions of the SMD casing.



Here is a PDF for the neopixel, it has the chip dimentions.
From this you can come close to the PCB measurements.
