Domino Mini PCI-e Reference Design

Is there Eagle reference design for Mini PCI-e interfacing to Domino Core for EC20 LTE module?

Sorry there is no reference. Actually they communicate with USB. It is physical PCIe but electronically USB. This should makes it easier for you.

Do you have any suggestion on how many pins I need and how to get it connected to USB on the Domino Core? That information would help us a lot in finalizing our product design before entering mass production. Thank you.
