Working with NVIDIA Jetson platforms often involves connecting MIPI CSI-2 cameras for real-time image processing. To ensure proper setup, it’s important to refer to accurate camera pinout details. This guide covers key pin functions, connector types, and best practices to help you set up your Jetson device and camera module correctly.
Introduction
NVIDIA Jetson camera pinout modules are widely used in embedded projects involving machine vision, robotics, and AI-based applications. One of the critical steps in any camera-related project using Jetson boards is connecting a MIPI CSI-2 camera module. This requires correct wiring between the camera and Jetson’s CSI connector, and that starts with knowing the pinout.
What Is a Camera Pinout?
The camera pinout refers to the assignment of signals to the physical pins on the connector used to attach the camera to the Jetson board. Each pin on the connector has a specific role, such as carrying power, ground, or image data.
Common Jetson Camera Connectors
NVIDIA Jetson boards come with either a 15-pin or a 22-pin CSI camera connector. The Jetson Nano Developer Kit typically uses a 15-pin connector, while newer models like Jetson Xavier NX and Orin use the 22-pin FPC connector. It’s important to use the correct camera interface and match it with the proper connector on the board.
Key Pin Functions
Typical pin functions on the Jetson CSI connector include:
GND – Ground connection
CAM_PWDN – Camera power down control
CAM_MCLK – Master clock for the camera
I2C_SCL / I2C_SDA – Serial communication lines for camera configuration
CSI_CLK / CSI_DATA – Differential pairs that carry video clock and data signals
Each Jetson board has its own configuration, so using the manufacturer’s datasheet is recommended when mapping the signals.
Importance of Proper Pin Mapping
Incorrect pin connections can result in camera detection failure, signal loss, or even hardware damage. Using a well-documented pinout prevents issues during device initialization. It’s also useful when building custom interface boards or when switching between different camera modules.
Camera Breakout Boards
Some developers prefer using breakout boards or adapter boards that convert the 22-pin layout to 15-pin (or vice versa). These boards often come with labeled pinouts, which can save time and reduce wiring errors.
Tips Before Wiring
Always power off the Jetson board before connecting or removing the camera.
Use flat flexible cables (FFC) of the correct pitch and orientation.
Secure the cable using the connector latch to avoid loose connections.
Verify the pinout from both the camera datasheet and Jetson hardware manual.
Conclusion
Setting up a camera on NVIDIA Jetson camera pinout boards requires more than just plugging in a cable. A clear understanding of the camera pinout is necessary to avoid signal mismatches and ensure the system works as intended. Whether you're working with a Jetson Nano, Xavier NX, or Orin, following proper pinout documentation is key to a stable camera connection.
