4.1 Connecting to Raspberry Pi
To connect the HQ Camera Module to your Raspberry Pi, follow these steps:
- Locate the CSI (Camera Serial Interface) port on your Raspberry Pi board. This is typically labeled "CAMERA".
- Gently pull up the plastic clip on the CSI connector.
- Insert the FPC (Flexible Printed Circuit) cable from the camera module into the CSI port, ensuring the silver contacts on the cable face the silver contacts in the connector.
- Push the plastic clip back down to secure the cable.
- For Raspberry Pi Zero models, an additional Raspberry Pi Zero v1.3 Camera Cable may be required (sold separately).

4.2 การติดเลนส์
The HQ Camera Module supports C-mount and CS-mount lenses. Use the included C-CS adapter ring for CS-mount lenses. Screw the desired lens onto the camera module's lens mount. Adjust the back focus ring as needed for optimal image clarity.
5. คู่มือการใช้งาน
After connecting the camera module, you will need to enable it in your Raspberry Pi's software settings. Refer to the official Raspberry Pi documentation for specific software configuration steps.
5.1 Camera Functionalities Demonstration
The following video demonstrates general camera functionalities such as autofocus, manual focus, and digital zooming. Please note that this video features a different camera module (Arducam 64MP Autofocus Raspberry Pi Camera Module B0399) but the principles of operation for these features are broadly applicable to the Raspberry Pi HQ Camera Module.

9. การบำรุงรักษา
- Keep the camera module and lenses clean and free from dust. Use a soft, lint-free cloth for cleaning.
- Avoid touching the sensor directly. Always use the dust cap when no lens is attached.
- Store the module in a dry, cool environment away from direct sunlight and extreme temperatures.
- ตรวจสอบให้แน่ใจว่าการเชื่อมต่อทั้งหมดแน่นหนาดีก่อนดำเนินการ
10 การแก้ไขปัญหา
- กล้องไม่ตรวจพบ:
- Check if the FPC cable is correctly inserted and secured in both the camera module and the Raspberry Pi's CSI port.
- Ensure the camera is enabled in your Raspberry Pi's software configuration (e.g., via
raspi-config). - Verify that your Raspberry Pi operating system is up to date.
- Poor image quality/focus:
- Adjust the back focus adjustment ring on the camera module.
- ตรวจสอบให้แน่ใจว่าเลนส์สะอาด ปราศจากรอยเปื้อนหรือฝุ่นละออง
- Check lens compatibility and ensure it is securely attached.
- โมดูลมีความร้อนสูงเกินไป:
- Ensure adequate ventilation around the Raspberry Pi and camera module.
- Consider using a heatsink or fan for prolonged high-load operations.
