The Raspberry Pi 5 introduces a new camera interface layout, replacing the older 15-pin CSI port with two 22-pin MIPI CSI connectors. These updated pinouts allow users to connect two cameras simultaneously, improving flexibility for applications like stereo vision and multi-angle imaging. This article breaks down the camera connector layout and helps developers navigate the changes introduced with the Pi 5.
Introduction
The Raspberry Pi 5 camera pinout brings several hardware improvements over its predecessor, including changes to how camera modules connect to the board. One of the most notable updates is the new camera interface setup, which now supports two MIPI CSI connectors for camera input.
Pinout Change from Raspberry Pi 4 to Raspberry Pi 5
In previous Raspberry Pi models, including the Pi 4, users were familiar with a single 15-pin CSI camera connector. With the Pi 5, this configuration has been replaced. The new board features two 22-pin MIPI CSI-2 interfaces—marked CAM0 and CAM1. These connectors support FFC (Flat Flexible Cable) interfaces and allow users to plug in two camera modules without needing an extra multiplexer board.
Connector Layout on the Board
The CAM0 and CAM1 connectors are located on opposite ends of the Raspberry Pi 5 board. Each one uses a 0.5mm pitch 22-pin layout. To connect standard Raspberry Pi camera modules that use the 15-pin connector, users will need an adapter cable that converts the 15-pin interface to 22-pin.
Supported Camera Use Cases
By supporting two camera inputs natively, the Raspberry Pi 5 opens up new project possibilities. Developers can now set up applications involving:
Stereo vision for depth perception
Multi-angle surveillance systems
Front and rear imaging setups in robotics
Simultaneous video streams for data processing
This dual connector setup removes the need for complex hardware modifications that were required in earlier models.
Pin Functions and Signal Types
The 22-pin camera connectors carry the following signals:
Differential data lanes (for image transmission)
Clock signal
I2C for camera control
Power supply lines (1.8V and 3.3V)
Ground connections
These signals follow the MIPI CSI-2 standard, which is widely used in camera integration across embedded systems.
Compatibility Considerations
If you're planning to use a standard Raspberry Pi camera module (like the V2 or HQ camera), keep in mind that these modules typically come with 15-pin cables. To connect them to the 22-pin interface on the Pi 5, a suitable adapter is necessary. Some manufacturers also offer camera boards with native 22-pin connectors, reducing the need for adapters.
Development Tips
When working with dual camera modules:
Use supported software libraries like libcamera for multi-camera control
Ensure your firmware is up to date to recognize both CAM0 and CAM1
Test camera functionality individually before integrating both
This approach can help isolate issues if one camera fails to initialize.
Conclusion
The Raspberry Pi 5 camera pinout reflects a shift toward better hardware support for vision-based projects. With two 22-pin MIPI CSI-2 connectors, the Pi 5 allows direct dual camera integration, supporting more advanced and flexible imaging setups. Whether you're building a robot, a monitoring system, or a vision-based AI prototype, this hardware change simplifies your workflow and adds more capability to your design.
