You can ask NVIDIA like this:
Option 1 (natural & clear):
“Can I design an SD card interface on my carrier board to use it as external storage when using the Jetson Orin Nano or Orin NX SoM?”
Option 2 (more detailed/technical):
“Is it possible to design an SD card (SDIO) interface on a custom carrier board and use it as external storage for the Jetson Orin Nano or Orin NX SoM? Are there any hardware or software limitations I should be aware of?”

Yes, you can design an SD card interface on your carrier board to use it as external storage when using the Jetson Orin Nano or Orin NX SoM. However, there are some considerations and limitations you should be aware of.
The Jetson Orin Nano Developer Kit carrier board design files are provided as a reference design, and both Jetson Orin Nano and Jetson Orin NX modules are compatible with this carrier board. The reference design includes an SD card interface, and you can replicate this feature on your custom carrier board.
To design an SD card interface on your custom carrier board, you can refer to the Jetson Orin Nano Developer Kit carrier board design files. The SD card interface is a standard SDIO interface, and you can use the same interface on your custom carrier board.
However, there are some hardware and software limitations you should be aware of:
In terms of specific hardware and software requirements, you can refer to the Jetson Orin Nano Developer Kit documentation and the NVIDIA Jetson Linux Developer Guide. These resources provide detailed information on the SD card interface and other features of the Jetson Orin Nano and Orin NX SoMs.
In comparison, the Jetson Orin Nano and Orin NX SoMs have similar requirements for the SD card interface, but there are some differences in terms of storage capacity and performance. The Jetson Orin Nano SoM has a smaller storage capacity than the Orin NX SoM, but it is still possible to use an SD card as external storage on both SoMs.
In summary, designing an SD card interface on your custom carrier board is possible, but you should be aware of the hardware and software limitations and ensure that your design is compatible with the specific SoM you are using.

Can you provide documentation on this topic?
Orin NX and Nano do not have SD interface on the SOM for custom board.
