OCuLink to PCIe adapter

Copyright (c) 2025 Antmicro

Overview

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

Key features

• Supports 4x PCIe link via an OCuLink connector over an x16 card edge connector
• PCIe cards can be powered via USB-C Power Delivery, EPS-12V or Molex Nano-Fit connector
• Optional on-board PCIe clock generator for SRSI and SRNS clocking configurations
• Mechanical outline optimized for dual slot PCIe cards
