Introduction
Arducam 5MP OV5647 Motorized Focus Camera Modules are designed for you to control the focus via software, so you can see closer and see where you want to see.
To learn more about autofocus with Raspberry Pi camera modules, we recommend you read Raspberry Pi Camera Autofocus: The Complete Guide.

Quick Start Guide
Hardware Setup
Ensure your Raspberry Pi is turned off.
1.Locate the camera port (CSI)
For Raspberry Pi Model A & B, it’s between the HDMI and audio port of the Raspberry Pi board.
2.Gently pull up on the edges of the connector’s plastic clip and avoid pulling it off
3.Insert the ribbon cable
Make sure the metal contacts are facing the HDMI connectors. Do not bend the flex cable, and make sure it’s firmly inserted.
4.Push the plastic clip down
Do it while holding the flex cable still, until the connector’s clip is back in place.
