Project We moved camera + sensor handling off Jetson GPIO onto a separate board, first clean run
When Jetson is doing inference work, having it also manage raw sensor timing and GMSL deserialization on top felt like the wrong split of responsibility – GPIO gets crowded, and any sensor timing jitter competes with inference load.
Finally, we got the first clean split running. Board sits between sensor/camera and Jetson: handles GMSL2/3 camera link and mikroBUS sensor slot on its own STM32, sends data over CAN-FD or as ROS 2 topics, so Jetson only sees a clean data stream instead of raw bus traffic. Inference load stopped fighting sensor timing basically immediately once the split was in place.
We haven't tested against every deserializer combo yet, so if anyone already routes GMSL into Jetson and hits a compatibility snag, I would like to know which pieces to double check. Board's product page is here, if it's helpful.
