The Raspberry Pi5 camera pinoutintroduces significant changes to camera connectivity with dual 22-pin MIPI CSI connectors. This article breaks down the new pinout configuration, highlights key differences from earlier models, and explains how to connect compatible cameras using the updated interface. Whether you're working with a single or dual camera setup, knowing the correct pin alignment and connector type is essential to avoid damage and achieve reliable operation.
Introduction
The Raspberry Pi5 brings several hardware upgrades, and among the most notable is its change in camera connection layout. Unlike previous Raspberry Pi boards that used a 15-pin CSI connector, the Pi5 now features dual 22-pin MIPI CSI-2 camera connectors, allowing more complex camera applications, such as stereo vision or multiple camera inputs.
Shift from 15-Pin to 22-Pin CSI Connectors
The 15-pin connectors found on earlier Raspberry Pi boards have been replaced by 22-pin connectors on the Pi5. This switch accommodates more data lines and additional control signals. It also makes it possible to support two camera modules simultaneously—one on each connector.
Layout and Signal Lines
Each 22-pin connector on the Raspberry Pi5 carries:
Two lanes for MIPI CSI-2 data
One clock lane
I²C signals for camera control
Power supply pins (3.3V and 1.8V)
Ground connections
CAM GPIO pins (used for camera sensor controls)
The pinout follows standard MIPI layout conventions, with dedicated pins for differential pairs that carry high-speed image data.
Physical Placement on the Board
The two connectors are labeled:
CAM0: Located near the top edge of the board, typically used as the primary camera port.
CAM1: Located near the lower right of the board and used for secondary camera modules.
Both connectors accept 22-pin flat flex cables and are compatible with supported camera modules via adapter boards if needed.
Adapter Boards for Legacy Camera Modules
If you have camera modules that use the 15-pin format (common with Raspberry Pi Camera Module v2 or third-party MIPI cameras), you’ll need an adapter board. These adapters convert the 15-pin interface to 22-pin while maintaining signal alignment. It's crucial to verify the orientation and voltage requirements before connecting.
Supported Camera Modules
The Raspberry Pi5 supports a growing list of MIPI CSI-2 camera modules. Compatible cameras must align with the board’s MIPI signal layout and voltage levels. Examples include:
Raspberry Pi Camera Module v3
Global shutter cameras
Infrared (IR) cameras
Custom MIPI sensor modules with proper configuration
Dual Camera Applications
Thanks to the two CSI connectors, Raspberry Pi5 camera pinout can handle stereo camera setups or run two different camera streams at once. This is beneficial for robotics, computer vision, machine learning, or monitoring systems that require multiple viewpoints.
Conclusion
Raspberry Pi5’s new camera pinout marks a shift towards more advanced image processing capabilities. With dual 22-pin connectors, users now have more flexibility and bandwidth to support complex camera applications. Knowing the correct pin layout and using the right connectors or adapters will ensure stable performance and hardware safety.
