GMSL2 enables high-speed camera links over a single automotive cable, allowing image sensors to be placed remotely from the processing unit.
This HAT enables the connection of two GMSL2 camera to a Raspberry Pi using a dedicated GMSL2 deserializer and CSI-2 video output.
The HAT connects to CSI port 1 and 2 of the Raspberry Pi, or compatible CSI-2 interface of another single-board computer.
Configuration and control are handled via the I2C interface on the 40-pin header.

The BE-IIS-GMSL-SER connects directly to one compatible CSI-2 camera module through its 22-pin FFC/FPC connector. It serializes the CSI-2 video stream onto a GMSL2 coaxial link and routes I2C control, camera reset, and camera-enable signals between the camera and the remote deserializer.
