From the project
PCB design which converts an OCuLink connector into x16 PCIe slot
This project includes PCB design files for an adapter card which break-routes a regular OCuLink x4 connector into x16 PCIe edge card slot. This board was designed for use with Antmicro Jetson Orin Baseboard OCuLink Expansion. Please inspect the schematics and verify the connection diagrams if you plan to use that board with any other OCuLink-compliant accessories. The PCB design files were prepared in KiCad 9.x
