I did, also saw 2 varients on datasheet from alibaba, for apa102c in 2020.
the six pads around is same, while the middle two differs
I hope the ground and power pad under the LED works , the routing would be much easier..
I currently draw my part in fritzing, and tried my best not to use another app (inkscape) to edit.
the results is a lot of pads, and some silkscreen "|" or "_" for part outlines
locating the pads precise is fairly easy with fritzing.
if anyone is interest in my results, i'll upload them later since i'm not with my files now.
the cons are that the pads are all individually, flipping them to the other layer requires so many clicks.and the system were slow if the copied part repeats too much.
with this apa102with2020, thats 8 small pads, and with 20LEDs that is alot of copy&pasting
and would likely to lag while moving/editing the whole led array.
Life It would be so happy if I can convert the objects directly in to a part,
or even just grouping them.
