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).
