Hi all,

I bought this led's form Aliexpress (https://www.aliexpress.com/item/32972803437.html?spm=a2g0o.productlist.main.35.410bcd71NEOy74&algo_pvid=c2421dc1-3335-4ea7-b01d-901c964ce7b2&algo_exp_id=c2421dc1-3335-4ea7-b01d-901c964ce7b2-17&pdp_npi=4%40dis!GBP!3.58!2.68!!!4.39!3.29!%40211b801b17119776822601038e5e69!12000036481556099!sea!GB!132318400!&curPageLogUid=ZPnjxcBzpjHz&utparam-url=scene%3Asearch|query_from%3A 3535 package) and I used the Adafruit footprint for them when I designed my board. I found the footprint doesn't match the led's (it is much smaller).
Where I can find the right footprint? I saw few on GitHub and KiCAD forums, but not of them matches the dimensions from the AliExpress listing.

Thank you
Gabi

Which CAD software are you using?

Kikad has footprint for SK6812 MINI 3535 leds:

You will have to make your own footprint.
The datasheet on this webpage shows the footprint

GrabCAD?

DigiKey's list of companies with 3D models...

Thank you for your reply, but the linked pdf is not the correct one. Pin in that datasheet are different than the pins from the actual product (shape, positions, dimensions).
Basically this I am trying to find, a datasheet with the correct dimensions and shapes.
Anyone?...

Then what you have is not an SK6812MINI as shown in the link you provided.
You probably have the 5050.
Does it measure 5mm x 5mm?

In Diptrace you can directly import patterns from SnapEDA

is this the footprint you need?

DipTrace.zip (20.8 KB)

in case yes I have attached a zip with a diptrace board with just that one component on the board and also the 3D model.

looks like this:
