Integrating with Custom Board

I found documentation regarding using a custom board camera (see attachment ). From what I understand, i just need to create the JSON file (blue circle) and modify the dwSensor (red circle). So, where can I find the dwSensor so I can customize it? And what are the next steps after modifying those components? How does the custom board integrate with the camera calibration procedure?

Thank you

Dear @jan.haenle,
Can you share details about your camera module?
