The Raspberry Pi5 camera pinout introduces a new camera interface setup with dual 22-pin connectors, replacing the traditional 15-pin design. This change brings more flexibility to camera integration but also requires users to refer to updated pinout specifications to ensure proper wiring and compatibility with camera modules. This article outlines key details about the camera pin layout, its purpose, and how to work with adapter boards when needed.
Introduction
Raspberry Pi boards have long been used in computer vision and camera-based projects. With the release of the Raspberry Pi5, the camera connection method has changed. Instead of a single 15-pin CSI camera port, the Pi5 includes two 22-pin connectors. These new ports offer higher data throughput and open up more options for projects involving single or dual-camera setups.
What Changed in Raspberry Pi5 Camera Pinout
The major change in Raspberry Pi5 is the shift from the traditional 15-pin to a 22-pin FPC (Flexible Printed Circuit) connector. The earlier models like Pi4 and Pi3 used a single camera interface, limiting the number of connected devices. The 22-pin connectors now support two cameras, allowing for more advanced configurations like stereo vision or wide-angle monitoring.
Purpose of the 22-Pin Connectors
Each 22-pin connector carries power, ground, clock, and data lanes required to transmit video signals from the camera to the processor. These connectors follow the MIPI CSI-2 standard, which is commonly used for camera interfaces in embedded systems. The dual connectors are labeled CAM0 and CAM1 on the board, and each supports high-speed data transfers needed for modern image sensors.
Compatibility with Older Camera Modules
If you're using a camera module designed for older Raspberry Pi versions, you'll likely need an adapter. Vadzo and other vendors provide 15-to-22-pin adapter boards that allow existing 15-pin camera modules to connect to the Pi5’s 22-pin interface. Careful attention must be paid to alignment and cable orientation to avoid damaging the board or camera.
Using Dual Cameras with the Pi5
The two camera connectors enable simultaneous use of two separate camera modules. This is useful for applications like stereo vision, machine vision, or surveillance systems requiring multiple angles. Both connectors operate independently and must be configured through the Pi’s software environment, typically using libcamera or other camera libraries.
Important Notes on Cable and Connector Handling
FPC cables are delicate and must be inserted correctly into the connectors. Make sure the cable contacts face the right direction and the locking mechanism is gently but firmly secured. Mismatched connections or forcing the cable may result in a poor signal or permanent hardware damage.
Conclusion
The Raspberry Pi5 camera pinout introduces a more advanced connection method that supports a broader range of imaging applications. The 22-pin layout, while different from older models, brings better flexibility for developers. With the right adapters and proper setup, both older and newer camera modules can work effectively with the Raspberry Pi5.
