A seedsigner user asked about support for this camera today (within the past hour) in the main telegram group, but it was written more as a customer-support error-report. The error reported was:
SystemError
PiCameraMMALError
exc.py 184 in mmal_check Failed to enable connection
It appears that CONFIG_VIDEO_IMX219 and similar arducam modules are NOT built-in at this time.
Looking at advertising for this camera, it appears to have motorized auto-focus control so I don't even know what hooks/ui would be appropriate in seedsigner if the auto-focus required adjustment; I've fiddled with my picamera focus just once in the past and once it's working I don't adjust again.
