CSI Camera Connector Compatibility for Jetson Orin Nano

Issue Overview

Users are experiencing difficulties finding and using the correct CSI camera connector for the Jetson Orin Nano Developer Kit. The main concerns include:

• Identifying the correct cable specifications (22-pin, 0.5mm pitch)
• Ensuring compatibility with the board’s CSI camera ports
• Avoiding potential issues with incorrect cable orientation or pin misalignment
• Finding reliable sources for the appropriate cable

The problem occurs during the hardware setup phase, specifically when trying to connect a camera to the Jetson Orin Nano board. This issue can prevent users from utilizing the CSI camera functionality, which is crucial for many AI and computer vision applications.

Possible Causes

1. Incorrect cable specifications: Using a cable with the wrong number of pins or pitch size can lead to connection issues or damage to the board.

2. Improper cable orientation: Connecting the cable in the wrong orientation can cause short circuits or prevent the camera from functioning correctly.

3. Incompatible camera modules: Some camera modules may not be fully compatible with the Jetson Orin Nano, even with the correct cable.

4. Quality issues with third-party cables: Cables from unreliable sources may not meet the required specifications or quality standards.

5. Lack of clear documentation: Insufficient or unclear information about the exact cable requirements can lead to users purchasing incompatible components.

Troubleshooting Steps, Solutions & Fixes

1. Verify cable specifications:

   • Ensure you are using a 22-pin, 0.5mm pitch Flexible Flat Cable (FFC) or Flexible Printed Circuit (FPC) cable.
   • The cable should be at least 150mm long to provide adequate flexibility for connection.

2. Check official documentation:

   • Refer to the Jetson Orin Nano Developer Kit Carrier Board Specification, specifically section 3.2 on Camera Connectors.
   • The board includes two 22-position flex (0.5 mm pitch) camera connectors (J20 and J219).

3. Use verified compatible cables:

   • Consider using the Arducam 4 cable, which has been tested and confirmed to work as a 15-pin to 22-pin conversion cable.
   • If using a 22-pin to 22-pin FPC, ensure that the camera pins match the dev-kit CSI connector pinout.

4. Correct cable orientation:

   • Pay close attention to the cable orientation when connecting it to the board and camera.
   • If using a cable that requires flipping, make sure to join two same-side FPC cables and flip the other end.

5. Test with known compatible cameras:

   • Start with camera modules known to work with the Jetson Orin Nano, such as the Raspberry Pi Camera Module v2.
   • Be aware that some cameras, like the Arducam UC-517, may require specific cable configurations.

6. DIY cable solution (temporary):

   • If you’re waiting for the correct cable, you can create a temporary solution by joining two same-side FPC cables and flipping one end.
   • This should only be used as a short-term fix while waiting for the proper cable.

7. Avoid potential shorts:

   • Inspect the cable and connectors for any signs of damage or manufacturing defects.
   • Ensure that the cable is seated properly in both the camera and board connectors.

8. Purchase from reliable sources:

   • Buy cables from reputable sellers or directly from manufacturers known for producing compatible Jetson accessories.
   • Be cautious when purchasing from generic online marketplaces, as the quality and specifications may vary.

9. Consult community resources:

   • Check the NVIDIA Developer Forums for the latest information and user experiences with different cable and camera combinations.
   • Join the NVIDIA Developer community to ask questions and share your findings with other Jetson users.

If you continue to experience issues after trying these steps, consider reaching out to NVIDIA support or consulting with experienced Jetson developers for further assistance.
