8layer open source design

Dear
I,m looking for a opensource 8 layer desing made in kicad. This is to test some software I’m working on. which means the design needs to be error free.

Thank you for the help and pointers!

My first goto would be:

I believe the Olinuxino A64 is a 6-layer board and there are some other multi-layers linked to there, but I have not looked at all of them.

Does it need to be exactly 8 layers, or just 8 or more?

Numato Opsis is 10-layers: https://github.com/timvideos/HDMI2USB-numato-opsis-hardware/

I suppose if you needed exactly 8, you could delete 2 of the GND plane layers and still have proper connectivity (although not proper signal integrity)

The more the better :wink:

And thanks for the tips !

After I posted the link to Made-with-kicad, I saw that one of the projects there ( CIAA-ACC) claimes a layer count of 12. That should be enough.
