Compatibility of Jetson Nano Expansion Boards with Jetson Orin Nano

Issue Overview

Users of the Nvidia Jetson Orin Nano Developer Kit are seeking information about the compatibility of expansion boards designed for the Jetson Nano with their Orin Nano device. Specifically, there is interest in mounting CAN expansion boards, GPS expansion boards, and relay expansion boards originally intended for use with the Jetson Nano. The lack of clear information regarding compatibility between these two platforms is causing uncertainty for users who wish to expand the functionality of their Orin Nano devices.

Possible Causes

1. Hardware differences: The Jetson Nano and Orin Nano may have different pin configurations or electrical specifications, potentially leading to incompatibility issues.

2. Form factor variations: The physical dimensions or mounting mechanisms of the expansion boards might not align with the Orin Nano’s design.

3. Software/driver incompatibilities: Even if physically compatible, the expansion boards may require different drivers or software support for the Orin Nano platform.

4. Power requirements: The Orin Nano might have different power delivery capabilities compared to the Jetson Nano, affecting the functionality of expansion boards.

5. Lack of manufacturer documentation: Insufficient information from both Nvidia and third-party expansion board manufacturers regarding cross-platform compatibility.

Troubleshooting Steps, Solutions & Fixes

1. Consult the carrier board specification:

   • Review the Jetson Orin Nano Developer Kit Carrier Board Specification document provided by Nvidia.
   • Compare the pin-out and electrical specifications with those of the Jetson Nano to identify potential compatibility issues.

2. Contact expansion board vendors:

   • Reach out to the manufacturers of the specific expansion boards you’re interested in (e.g., Waveshare for the mentioned products).
   • Inquire about compatibility with the Jetson Orin Nano platform and any necessary modifications or adaptations.

3. Examine physical compatibility:

   • Compare the physical dimensions and mounting points of the Orin Nano Developer Kit with the Jetson Nano.
   • Determine if any mechanical adjustments would be necessary to fit the expansion boards.

4. Research community experiences:

   • Search Nvidia developer forums and other online communities for users who have attempted to use Jetson Nano expansion boards with the Orin Nano.
   • Look for any successful implementations or workarounds shared by the community.

5. Evaluate software compatibility:

   • Check if the expansion board drivers and software are compatible with the Jetson Linux version running on the Orin Nano.
   • Look for any available updates or alternative drivers that might support the Orin Nano platform.

6. Consider alternative solutions:

   • If direct compatibility is not possible, explore expansion boards specifically designed for the Orin Nano.
   • Investigate the possibility of using USB-based alternatives for the desired functionalities (e.g., USB-to-CAN adapters, USB GPS modules).

7. Prototype cautiously:

   • If attempting to connect Jetson Nano expansion boards to the Orin Nano, start with non-invasive tests.
   • Use multimeters to verify voltage levels and pin mappings before making any connections.
   • Begin with simple expansion boards (e.g., GPIO expanders) before moving to more complex ones.

8. Consult Nvidia support:

   • If no clear information is available, consider opening a support ticket with Nvidia to inquire about official compatibility statements or recommendations.

9. Document and share findings:

   • If you successfully adapt Jetson Nano expansion boards for use with the Orin Nano, document your process and share it with the community to help others facing similar challenges.

Remember that attempting to use incompatible hardware may risk damaging your Jetson Orin Nano Developer Kit. Always prioritize caution and thorough research before connecting any non-certified expansion boards to your device.
