Jetson Orin Nano Developer Kit: SD Card Interface Inquiry

Issue Overview

Users are seeking information about the SD card interface for the Jetson Orin Nano Developer Kit. Specifically, there is confusion regarding the availability of design files and schematics for the Orin Nano, as opposed to the Orin NX. The main concern is the inability to locate the micro SD card interface in the available schematics, which has led to questions about its support and implementation in the Orin Nano developer kit.

Possible Causes

1. Documentation Mismatch: The design files downloaded by the user were for the Orin NX instead of the Orin Nano, leading to confusion about the specific hardware layout.

2. Hardware Similarity: The carrier boards for the Orin NX and Orin Nano may share similar designs, making it difficult to distinguish between their schematics.

3. Feature Absence: The external SD card interface might not be a supported feature on the Jetson Orin Nano Developer Kit, contrary to user expectations.

Troubleshooting Steps, Solutions & Fixes

1. Verify Documentation:

   • Double-check that you have downloaded the correct documentation for the Jetson Orin Nano Developer Kit.
   • Visit the official NVIDIA Jetson documentation website to ensure you have the most up-to-date information.

2. Understand Hardware Commonalities:

   • Be aware that the carrier board schematic is the same for both the Orin NX and Orin Nano.
   • When reviewing schematics, focus on the common elements between the two models.

3. SD Card Interface Clarification:

   • Note that external SD card design is not supported on the Jetson Orin Nano Developer Kit.
   • Consider alternative storage options that are supported by the developer kit, such as onboard eMMC or NVMe SSDs.

4. Seek Official Support:

   • If you require further clarification, post your inquiry in the appropriate Jetson category on the NVIDIA Developer forums.
   • Navigate to the "Jetson Orin Nano" subcategory for the most relevant assistance.

5. Explore Alternative Solutions:

   • If an SD card interface is crucial for your project, consider using USB-based SD card readers as an external solution.
   • Investigate the possibility of using network-attached storage (NAS) or other remote storage options for additional capacity.

6. Stay Informed:

   • Regularly check the NVIDIA Jetson community forums for updates, as new information or workarounds may be shared by other developers or NVIDIA staff.
   • Subscribe to NVIDIA Developer newsletters or follow their social media channels for announcements about hardware updates or new developer kits.

By following these steps and understanding the hardware limitations, developers can make informed decisions about storage solutions for their Jetson Orin Nano projects and explore alternative approaches if necessary.
