Raspberry Pi boards offer camera support through the CSI connector. The pin layout differs across models, and using the correct pinout is key when setting up a camera module. This article outlines the pin configurations of 15-pin and 22-pin connectors and provides practical setup steps for connecting a camera properly.
Introduction
Camera modules designed for Raspberry Pi camera pinout connect to the board using the Camera Serial Interface (CSI). Depending on the board version, the number of pins and their layout may differ. Knowing which pins handle data, power, and control signals can help users avoid common connection problems.
Connector Types Across Raspberry Pi Models
Different Raspberry Pi boards use different connectors. Models such as Raspberry Pi 3 and 4 feature a 15-pin CSI connector. Newer boards like the Raspberry Pi 5 include a 22-pin connector, allowing for more data lanes and other improvements.
15-Pin Camera Connector Pin Layout
This connector is most commonly seen on earlier Raspberry Pi boards. The pin layout includes:
Ground lines
Data transmission lanes (Lane 0 and Lane 1)
Clock signals
Power and I2C pins
These pins are arranged in a single row and support the official V1 and V2 camera modules from Raspberry Pi.
22-Pin Camera Connector Pin Layout
This connector is used in newer Raspberry Pi models, including the Raspberry Pi 5 and the Compute Module boards. It includes:
More data lanes
Additional ground and power lines
Control lines for newer camera features
This layout allows for dual-camera setups and better performance in certain video applications.
How to Connect a Camera Module
Before making any connections, make sure your Raspberry Pi is powered off. Insert the ribbon cable into the CSI port, ensuring the contacts are aligned correctly. After securing the cable with the latch, power on the board. You can enable the camera and run basic tests using tools like lib camera or through configuration settings.
Using Adapters for Compatibility
Adapter boards can help when the camera and the Raspberry Pi camera pinout use different connector types. For instance, a 22-pin to 15-pin adapter makes it possible to use older cameras with a Raspberry Pi 5. These adapters handle the necessary signal mapping and keep your setup stable.
Conclusion
Setting up a camera on a Raspberry Pi starts with identifying the correct connector and pin layout. Whether using a 15-pin or 22-pin CSI port, proper alignment and wiring are essential for stable performance. Refer to board specifications before connecting any hardware.
