Raspberry Pi5 introduces a 22-pin camera pinout, replacing the earlier 15-pin configuration used in previous models. This new layout supports higher data rates and compatibility with advanced camera modules. In this article, we break down the pin structure, functions, and how to connect a camera to the Raspberry Pi5 using the correct interface.
Introduction
The Raspberry Pi5 camera pinout brings several hardware improvements, and one of the most notable changes is in the camera connector. Unlike previous models that relied on a 15-pin MIPI CSI connector, the Raspberry Pi5 uses a 22-pin configuration. This change affects how camera modules are connected and opens the door for better data handling and expanded peripheral support.
Overview of the Raspberry Pi5 Camera Connector
The Pi5 features two FFC (Flat Flexible Cable) connectors for attaching cameras and displays. These connectors use a 22-pin layout and are physically smaller than the traditional 15-pin CSI connector seen on earlier models like the Pi4. The shift to 22 pins allows additional signal lanes, improving support for higher-bandwidth applications.
Raspberry Pi5 Camera Pinout Breakdown
Here’s a brief look at what each pin in the 22-pin layout is typically assigned to:
Power Supply Pins: 3.3V, 1.8V, and GND lines for camera module power.
I2C Pins: Used for camera control communication.
Clock Lines: For transmitting clock signals to the camera.
Data Lanes: MIPI CSI-2 lanes used to transmit video data from the sensor to the Pi.
GPIO (optional use): Some pins may allow general-purpose I/O functionality, depending on the module.
These pins are arranged in a tightly packed format on the board and require a matching 22-pin FFC cable and compatible camera module.
Compatibility and Adapters
Most existing camera modules designed for the Pi4 or Pi3 use a 15-pin interface. To use these with a Raspberry Pi5, you’ll need a 22-pin to 15-pin adapter. These are available from third-party manufacturers and make it possible to continue using older modules with the new board.
How to Connect a Camera to Raspberry Pi5
Power off the Raspberry Pi5. Always begin by shutting down the board to prevent hardware issues.
Locate the 22-pin camera connector. It’s positioned near the board edge and is clearly labeled.
Insert the FFC cable. Make sure the contacts are facing the correct side (usually toward the board).
Secure the cable using the latch. Gently press the latch down to hold the cable in place.
Boot up the Raspberry Pi5 and enable the camera interface via the system configuration menu.
Conclusion
The Raspberry Pi5 camera pinout is designed to support the latest camera modules through a 22-pin MIPI CSI-2 interface. This shift offers better support for high-resolution imaging and faster data transfers. While it introduces a new connector type, adapters help bridge the gap with older hardware. Knowing the correct pin layout and connection process is essential for any camera-based project using the Pi5.
