This bus follows the ribbon cable that connects the camera board to Raspberry Pi. The camera communicates with the Raspberry Pi's BCM2835 processor through CSI bus, a higher-bandwidth link that relays pixel data from the camera to the processor. The CSI bus can handle exceptionally high data rates and is only used to transport pixel data. Pi camera module is attached with Raspberry Pi zero by CSI interface. This interface makes use of the specific CSI interface, which was created with cameras in mind. In this tutorial, we are going to interface the Pi camera module with Raspberry Pi Zero W and try taking pictures and record video.

Raspberry Pi camera module is a tiny board that can be interfaced with Raspberry Pi for capturing pictures and streaming videos. In our previous tutorials, we used Pi camera module with Raspberry 3 & 4 to build many OpenCV based projects.
