SUMMARY

The discussion centers on the availability of PCI Express (PCIe) cable systems for board-to-board connections, specifically focusing on the Molex iPass cabling system. While the iPass system supports PCIe connections, it is designed with a custom pinning configuration (68 pins for x8 PCIe) that prevents compatibility with standard PCIe x8 cards or slots. Participants express interest in alternative solutions, particularly for laptop applications.

PREREQUISITES
  • Understanding of PCI Express architecture and specifications
  • Familiarity with Molex iPass cabling systems
  • Knowledge of PCIe board edge connectors
  • Experience with custom cabling solutions
NEXT STEPS
  • Research alternative PCIe cabling solutions for board-to-board connections
  • Explore compatibility of Molex iPass with existing PCIe hardware
  • Investigate custom pinning configurations for PCIe connections
  • Learn about PCIe standards and specifications for different form factors
USEFUL FOR

Hardware engineers, system designers, and anyone involved in developing or optimizing PCIe connectivity solutions.

Is there a PCIe cable system available that attaches to a standard PCIe Board Edge Connector or Mother Board PCIe slot?

I see Molex has the iPass cabling system for PCIe board to board connections. But based on the Molex connection pinning (68pins for x8 PCIe) it is more of a custom solution and cannot be adapted to connect to an existing standard PCIe x8 Card/Slot.

Hi,

Did you figure out?
I found some solution for laptop only.
I'm interesting in the solution you got.

Eric.
