Hardware Connection
-
Locate the camera connector (CSI). It’s on the side of the carrier board, opposite to the GPIO pins.
-
Pull up on the plastic edges of the camera port. Do it gently to avoid pulling it off.
- Push in the camera ribbon. Make sure the contacts are facing the heatsinks. Do not bend the flex cable, and make sure it’s firmly inserted into the bottom of the connector.
