Mounting holes for Jetson Xavier NX SoM


I am designing a carrier card for Jetson Xavier NX SoM. As I understand, for mechanical support of SoM, I need to provide 2 mounting holes in my carrier card. I am going through P3509 Schematics & layout. In schematics I can see 2 mounting holes shown MEC3A & MEC3B but in the layout I can see 6 additional mounting holes. Can I know what are those mounting holes used for?
Best regards, Bhagavath

P3509 is devkit carrier. For custom design, please refer to the module data sheet for the mounting holes as below picture showing.

Thanks for the quick response.
I have already seen this page in the datasheet. However, I couldn’t find the distance from DIMM connector pin to 2 mounting holes in datasheet. I have also gone through “OEM product design guide” but no mention about mechanical details in that document. For my carrier card design, I should know the exact gap between DIMM connector & mounting holes so that it will be aligned properly with SoM.

Best regards,

Please refer to the Orin NX STEP model file or PCB layout file in DLC.

OK, thanks. Is there any pdf files available with mechanical details of connector & mounting holes for carrier card design?

No, there is no such file.
