I have bought a Seed Studio Jetson AGX Orin H01, and I need to connect several 4-lane MIPI cameras.

My questions are.

1.- What type of screwdriver is necessary to open the box?

2.- Is the Seeed Studio Jetson AGX Orin H01 compatible with Seeed Studio J501-GMSL Extension Board?

3.- Where can I find an adaptor from 4-lane MIPI to GMSL?

Hi there! If you’re trying to connect multiple cameras, the method really depends on the specific board you’re using and its available interfaces…

for boards like the reComputer J4011 (Jetson Orin NX), you can support dual CSI camera inputs, but it often comes down to the software layer. A common issue is the OS image—make sure you are using the official Seeed Jetson OS Image as generic NVIDIA images sometimes don’t enable all the ports on Seeed carrier boards.

a few quick things to check::

  1. Configuration: You might need to use the sudo /opt/nvidia/jetson-io/jetson-io.py tool to enable both camera headers.

  2. Wiki Check: I highly recommend looking at the Seeed Camera Support Wiki for your specific model—it lists compatible sensors (like IMX219 or IMX477) and the specific driver steps needed.

  3. Power: Multiple cameras can pull significant current; ensure your power supply can handle the extra load…..

If you can share the exact bboard and camera models you’re using, it’ll be much easier for the community to help you with the specific commands! :blush:

Use a small Phillips #0/#00 to open the box. The H01 should work with the J501-GMSL, but double-check power and pins. For 4-lane MIPI to GMSL, contact Seeed or look for specialised converters, they’re rare.

I don’t think it’s compatible — the layout is different on the AGX Orin H01. Has anyone found a GMSL camera board that works with the H01?

Hi there,

And Welcome here…

So, The compatibility issue you are encountering stems from the physical design of the Jetson AGX Orin H01 Kit. While the official NVIDIA Jetson AGX Orin Developer Kit features standard camera extension headers designed to interface directly with popular GMSL/GMSL2 deserializer boards, the Seeed Studio H01 carrier board breaks out its 16-lane MIPI CSI-2 interfaces differently.

Because the H01 layout is customized into standard high-density MIPI connectors instead of the standard DevKit camera headers, you cannot plug common commercial GMSL deserializer boards (like those from Connect Tech or TechNexion) directly onto the H01 board without a specialized adapter or custom cabling.

If you are looking for a working GMSL solution on this specific layout, here are your best paths forward:

1. Specialized MIPI CSI-2 to GMSL Converters

To use GMSL cameras with the H01, you must leverage its 16-lane MIPI CSI-2 ports. This requires an external deserializer board that accepts MIPI ribbon/coaxial inputs rather than one designed as a direct plug-in “hat” for the standard NVIDIA DevKit.

  • Vendors like e-con Systems offer custom
    deserializer boards (such as those using the Maxim MAX9296 or MAX96724 chips) that can interface via standard MIPI CSI-2 connections, though you may need custom multi-lane MIPI flexible flat cables (FFC) to map to Seeed’s specific H01 pin layout.

As mentioned in the forum thread, finding pre-made 4-lane MIPI to GMSL adapter boards that map perfectly out of the box to the H01 is exceptionally rare, and often requires reaching out directly to Seeed Studio’s enterprise support or a camera partner like Forecr or e-con Systems for a custom pin-mapped cable.

2. The Official “reComputer J501” Alternative

If your project absolutely requires native, plug-and-play GMSL multi-camera support without custom hardware engineering, the community consensus is usually to pivot carrier boards.

Seeed Studio explicitly designed the reComputer Mini J501 Carrier Board with GMSL to solve this exact problem. It features an integrated GMSL extension slot built directly onto the single board. Seeed even sells this as a complete reComputer Jetson AGX Orin Developer Kit GMSL Bundle that includes a pre-tested Sensing SG3S-ISX031C-GMSL2F 3MP camera and the necessary Mini-Fakra 4-in-1 cabling.

Summary: If you must stick with the H01, you will need to source an external deserializer module and custom map the MIPI CSI-2 lanes. If you want a seamless GMSL setup, migrating the AGX Orin module over to Seeed’s J501 carrier board is the most reliable path.

Thank you for this very detailed reply. I’m going to move forward with the Mini J501, as I think it’s the only realistic solution left for my project, and it is compatible with the core module from the H01.

It’s a bit unfortunate that there are so few compatible GMSL solutions available for the H01 platform without requiring custom adapters or cabling.

In any case, thank you again for taking the time to provide such a complete explanation.
