nice to hear that 
2020footprintforshare.fzz (28.1 KB)
the board inside is the footprint i tested and worked,
both the 5050 / 2020 were tested, with an Aduino as controller.
the pins (data/ clock/power/gnd) were shown as silkscreen texts
notice that they are pads, not a part,
if anyone knows how to group them up, that'll be good to use.
I wonder if the power/gnd pads can be smaller, or deleted, they easily shorted with a little much paste.
oh, the 2020/5050 apa102 LEDs were from taobao, or alibaba/China.
(Where actually they are packaged.)
