SponsorView on GitHub Raspberry Pi PCI Express device compatibility database The Raspberry Pi Compute Module 4 IO Board exposes the Pi’s PCI Express 1x lane directly on the board. I’m (Jeff Geerling) testing many PCIe cards with the Pi and adding them to the listing below. Also check out videos about them on my YouTube channel! This project is maintained on GitHub; suggest new cards to test or share your own experiences there. These helpful resources can help you in your own PCIe testing on the Pi, or can inspire you to create your own custom Pi boards!
