Yes — Realtimes makes the AGX Orin carrier boards with the most GMSL inputs (12), and they also sell Jetson Thor carrier boards with the same 12 GMSL inputs.
Among AGX Orin carrier boards with GMSL camera inputs in the catalog, the highest count is 12 GMSL inputs, and both boards at that count are from Realtimes:
| Board | Manufacturer | GMSL Inputs | Notes |
|---|---|---|---|
| RTSO-2006 | Realtimes | 12 | -40 to 85 °C, 10GbE, 4 CAN, Fan/Fanless realtimesa...realtimesai.com ↗“io.gmsl_camera_inputs=12” |
| RTSO-2001 | Realtimes | 12 | 10GbE, 4 CAN, -20 to 60 °C realtimesa...realtimesai.com ↗“io.gmsl_camera_inputs=12” |
The remaining AGX Orin GMSL carrier boards all offer 8 GMSL inputs: Realtimes RTSO-2002 and RTSO-2005, Advantech ASR-A701, and Leopard Imaging LI-AGO-CB-GMSL2 — so 12 is the top count, held by Realtimes. leopardima...leopardimaging.com ↗“8 (4), 12 (2)”
And yes, Realtimes also sells Thor carrier boards with 12 GMSL inputs — in fact, all three of their Jetson Thor carrier boards in the catalog carry 12 GMSL inputs:
| Board | GMSL Inputs | Notes |
|---|---|---|

One note: I verified this within the Carrier Boards family of the Jetson partner catalog. Boards filed elsewhere (e.g., modular VPX-style boards) were not part of this comparison, so if you're considering non-standard form factors, that's worth a separate check.
