This article provides a breakdown of the NVIDIA Jetson camera pinout, detailing the configurations of 15-pin and 22-pin MIPI CSI-2 connectors. It explains the function of each pin, differences in connector types across Jetson boards, and how to connect compatible camera modules accurately.
Introduction
NVIDIA Jetson camera pinout boards are frequently used in embedded systems for computer vision and machine learning. These boards often require MIPI CSI-2 cameras, which are connected through either 15-pin or 22-pin interfaces. Accurate pinout reference is essential for correct hardware setup and communication.
MIPI CSI-2 Interface Support
Jetson platforms such as the Nano, Xavier NX, and Orin NX use MIPI CSI-2 for high-speed camera communication. The physical interface for this connection varies depending on the board:
15-pin CSI connector — Common on Jetson Nano Developer Kit
22-pin CSI connector — Found on Jetson Xavier NX, Orin NX, and others
15-Pin Connector Pinout
The 15-pin layout supports basic camera modules. Each pin has a specific role:
Pins 1, 4, 7, 10, 15: Ground
Pins 2–3: Differential Pair for Data Lane 0
Pins 5–6: Differential Pair for Data Lane 1
Pins 8–9: Clock Signal (Positive and Negative)
Pins 11–12: I2C Serial Clock and Data for camera communication
Pin 13: Camera Power
Pin 14: GPIO or Camera Enable
22-Pin Connector Pinout
The 22-pin setup supports more advanced camera modules with extra data lanes:
Pins 1–2: Power supply to camera
Pins 3–4: Ground
Pins 5–6: Clock signals
Pins 7–10: Two pairs of data lanes
Pins 11–14: Optional additional data lanes
Pins 15–16: I2C SCL and SDA
Pins 17–18: GPIO or RESET
Pins 19–20: Power Enable or Standby
Pins 21–22: Ground
Compatibility Considerations
Before setting up a camera with a Jetson board, it’s important to confirm pin compatibility. Misalignment between pinouts can lead to failed communication or damage. Adapter boards can be used to connect 15-pin cameras to 22-pin slots or vice versa, depending on the setup.
Installation Tips
Double-check voltage levels to prevent damage
Secure connections firmly to avoid disconnection
Configure the I2C bus correctly in software
Reference official Jetson documentation for device tree settings
Conclusion
Knowing the pinout of Nvidia Jetson camera pinout connectors is essential for reliable camera integration. Whether you're working with a basic 15-pin camera or a more advanced module using a 22-pin connector, pin-level accuracy ensures the camera communicates correctly with the board. Reviewing the hardware layout before powering the system helps avoid connection problems.
