Dear NVIDIA Support Team,

I am currently designing a custom carrier board for NVIDIA Jetson Orin Nano and Jetson Orin NX modules.

I would like to ask whether it is technically feasible and officially supported to design an SD card interface directly on the carrier board for these modules. Specifically, I would appreciate your guidance on the following points:

  1. Can Jetson Orin Nano and Jetson Orin NX support an external SD card slot on a custom carrier board?
  2. Are there any differences in SD card interface support between Jetson Orin Nano and Jetson Orin NX?
  3. Which interface or pins should be used for SD card connection on the carrier board?
  4. Are there any hardware design guidelines, reference schematics, or layout recommendations that NVIDIA provides for this use case?
  5. Are there any limitations regarding booting from SD card or using the SD card only as external storage?

We would like to confirm this before finalizing our carrier board design to ensure compatibility and reliability.

Thank you for your support. I look forward to your guidance.

Best regards,

Based on the provided context, I will address your questions regarding the design of an SD card interface on a custom carrier board for Jetson Orin Nano and Jetson Orin NX modules.

  1. Can Jetson Orin Nano and Jetson Orin NX support an external SD card slot on a custom carrier board?

According to the community solutions, there is no SD/SDIO interface on the Orin Nano Module, and it is not possible to use an SD card slot on a production Orin Nano module. You have to use other interfaces like USB or NVMe SSD. Similarly, for Orin NX and Nano, there is no SD interface on the SOM for custom boards.

  1. Are there any differences in SD card interface support between Jetson Orin Nano and Jetson Orin NX?

Both Jetson Orin Nano and Jetson Orin NX do not have SD interfaces on the SOM for custom boards, so there are no differences in this regard.

  1. Which interface or pins should be used for SD card connection on the carrier board?

Since there is no SD/SDIO interface on the Orin Nano Module, you cannot use SD card pins for connection on the carrier board.

  1. Are there any hardware design guidelines, reference schematics, or layout recommendations that NVIDIA provides for this use case?

The provided context does not mention any specific guidelines or recommendations for designing an SD card interface on a custom carrier board for Jetson Orin Nano or Jetson Orin NX.

  1. Are there any limitations regarding booting from SD card or using the SD card only as external storage?

As mentioned earlier, it is not possible to use an SD card slot on a production Orin Nano module, so booting from an SD card or using it as external storage is not supported.

In summary, designing an SD card interface directly on the carrier board for Jetson Orin Nano and Jetson Orin NX modules is not technically feasible or officially supported due to the lack of SD/SDIO interfaces on the modules. You should consider using alternative interfaces like USB or NVMe SSD for external storage.

I could not find clear support for SD card interface design guidelines or recommendations in the provided Jetson Orin Nano documentation.

Jetson Orin NX and Orin Nano do not route the SD card signals to the SO-DIMM connector, so SD card support cannot be added on a carrier board. Storage options are limited to NVMe.

The only Jetson Orin with SD card support is the Orin Nano Super Developer Kit, which has a micro SD socket integrated into the module itself, not the carrier board.
