Raspberry Pi camera pinout refers to the layout of pins used to connect camera modules through the CSI (Camera Serial Interface) port. Knowing how the pins are arranged is important for setting up your camera correctly. This article gives a clear breakdown of the pin configuration and how to use it for your camera projects.
Introduction
The Raspberry Pi is widely used for camera-based projects including time-lapse photography, motion detection, and DIY security systems. A key step in setting up a camera is knowing how to connect it to the board. This is where the camera pinout becomes important. The pinout provides a map of the electrical connections between the board and the camera module.
What is the Raspberry Pi Camera Pinout?
The camera pinout refers to the layout of the pins found in the Camera Serial Interface (CSI) connector on the Raspberry Pi. This connector is usually a flat, white port located near the HDMI or display connectors. The pins are arranged in a specific pattern that supports high-speed data transfer between the Pi and the camera.
Types of Connectors
There are two main types of CSI connectors found on Raspberry Pi models:
15-pin connector: Common on models like the Raspberry Pi 3 and Raspberry Pi 4.
22-pin connector: Found on the Raspberry Pi Zero and some Raspberry Pi 5 variants.
Each connector uses a ribbon cable that plugs directly into the camera port.
15-Pin CSI Camera Pinout
For Raspberry Pi boards with a 15-pin connector, the pin functions are typically as follows:
Ground
CAM_D0_N
CAM_D0_P
Ground
CAM_D1_N
CAM_D1_P
Ground
CAM_CK_N
CAM_CK_P
Ground
CAM_IO0
CAM_IO1
CAM_IO2
CAM_IO3
Ground
These pins carry differential data pairs (D0/D1) and clock signals (CK), as well as a few control lines.
Camera Connection Tips
When connecting a camera module, make sure the Pi is powered off. Insert the ribbon cable with the silver connectors facing toward the HDMI port (in most models). Gently push down the plastic clip on the CSI port to lock the cable in place. Power on the Pi only after the connection is secure.
Common Use Cases
Some common projects that require camera modules include:
Smart doorbell systems
Wildlife monitoring
Face detection or tracking systems
Barcode or QR code scanning
Conclusion
Knowing the Raspberry Pi camera pinout is crucial when setting up camera-based projects. Whether you're using a standard 15-pin camera or working with a smaller 22-pin version, the layout of the connector affects how well your module communicates with the board. Accurate connections help avoid hardware damage and ensure reliable performance.
