Hello, I’m looking to design a dedicated adapter board to connect an external E1.S Form Factor NVMe SSD to the Jetson AGX Orin DevKit via the PCIe Mini-SAS connector. I know that in previous forum posts, Nvidia support has pointed to using USB3 PD instead of the PCIe Mini-SAS but I need the higher performing R/W speeds of PCIe over USB3 PD. Therefore, can you please provide the pinout diagram/pin definition to the SFF-8644 PCIe x4 Mini-SAS connector?

Thanks

Please refer to the P3737_A04 reference schematic and Orin carrier board specification in DLC for the connector info of devkit carrier board.
