Keith & Koep offers different Camera options to use with their modules.
Options are: USB-camera, PAL-Camera and a Raspberry-Pi camera-connector (MIPI-CSI), which is found on many Baseboards.
We can supply an OV5640 camera-board.
How the camera is used may differ between Linux distributions.
On Debian & Android different Apps are available, to allow simple testing.
On Linux Yocto you can use GStreamer to test the camera.
See GStreamer documentation and the NXP 'Linux User Guide' for details and examples.
Example: i.MX 8M Mini; Output OV5640 camera to wayland desktop:
gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,width=640,height=480,framerate=30/1 ! waylandsink -v
