Raspberry Pi camera pinoutplays a vital role in setting up camera modules with accuracy. Whether using a 15-pin or 22-pin CSI interface, each pin has a specific function. This article walks through the layout, pin mapping, and proper connection methods.
Introduction
The Raspberry Pi has become a reliable tool for camera-based projects, from home monitoring systems to object tracking. To get these applications working, proper camera integration is key—and this starts with knowing the Raspberry Pi camera pinout.
CSI Interface Overview
The Camera Serial Interface (CSI) is the primary port used to connect camera modules to the Raspberry Pi. There are two standard pin configurations used across models:
15-pin connector: Found on models like Raspberry Pi 4, 3, and Zero
22-pin connector: Used in Raspberry Pi 5 and Compute Modules
15-Pin Pinout Layout
On the 15-pin connector, the layout includes the following important signals:
GND (Ground)
CAM_CLK (Clock signal)
CAM_D0 / D1 (Data lines)
CAM_CSI (Control signals)
These pins are arranged to carry power and data from the camera module to the board’s processor.
22-Pin Pinout Layout
The newer 22-pin interface provides more signal lines and supports additional features:
Additional ground and power lines
Extra data lanes for higher bandwidth
Improved performance with dual camera setups (with supported boards)
This layout is typically seen in advanced Raspberry Pi boards like the Pi 5, which supports two camera inputs.
Adapters and Compatibility
If you’re moving between models with different pin layouts, adapter cables are available. A 15-to-22 pin adapter lets you connect older cameras to newer boards, and vice versa. Always check pin alignment when using adapters to avoid shorts or signal mismatches.
Important Tips
Always power off your Raspberry Pi camera pinout before connecting or disconnecting the camera.
Match the notches on the CSI connector and ribbon cable to ensure correct orientation.
Verify the camera module is compatible with your Pi model before installation.
Conclusion
Knowing the Raspberry Pi camera pinout is essential for setting up camera modules without damaging the hardware. Whether working on a basic video project or a multi-camera system, following the correct pin layout ensures your connection is accurate and stable.
