Overview

The Juxi Technology CSI Camera Module is designed for the NVIDIA Jetson Orin Developer Kit, delivering low-latency, high-bandwidth video via the CSI (Camera Serial Interface) interface. Ideal for AI vision inference, robot perception, and edge computing.

Features:

• CSI-2 interface, direct connection to Jetson Orin
• Ready-to-use OpenCV and GStreamer examples
• Low-latency video transmission
• UVC protocol compatible

Specifications

Parameter	Spec
Interface	CSI-2 (MIPI)
Platform	NVIDIA Jetson Orin series
Video Format	RAW / YUV
SDK	JetPack 5.0+
Framework	GStreamer / OpenCV

Quick Start

Hardware Connection

1. Power off the Jetson Orin
2. Connect one end of the CSI ribbon cable to the camera module
3. Insert the other end into the CSI connector on the Jetson Orin board
4. Ensure correct orientation (metal contacts facing the board)

⚠️ Warning: Always connect the CSI cable with power OFF to avoid hardware damage.

Verify Device Detection

ls /dev/video*
v4l2-ctl --list-devices
v4l2-ctl --list-formats-ext -d /dev/video0

Python Code Example

Install dependencies:

sudo apt install -y python3-opencv

GStreamer + OpenCV CSI capture:

import cv2

def gstreamer_pipeline(
    sensor_id=0,
    capture_width=1920,
    capture_height=1080,
    display_width=960,
    display_height=540,
    framerate=30,
    flip_method=0,
):
    return (
        "nvarguscamerasrc sensor-id=%d ! "
        "video/x-raw(memory:NVMM), "
        "width=(int)%d, height=(int)%d, "
        "format=(string)NV12, framerate=(fraction)%d/1 ! "
        "nvvidconv flip-method=%d ! "
        "video/x-raw, width=(int)%d, height=(int)%d, format=(string)BGRx ! "
        "videoconvert ! "
        "video/x-raw, format=(string)BGR ! appsink"
        % (
            sensor_id, capture_width, capture_height,
            framerate, flip_method, display_width, display_height,
        )
    )

cap = cv2.VideoCapture(gstreamer_pipeline(), cv2.CAP_GSTREAMER)
if not cap.isOpened():
    print("Cannot open CSI camera")
    exit()

while True:
    ret, frame = cap.read()
    if not ret:
        break
    cv2.imshow('CSI Camera', frame)
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break

cap.release()
cv2.destroyAllWindows()

FAQ

Q: Camera not detected?

A: Verify the ribbon cable is correctly connected and oriented. Run ls /dev/video*. If still not detected, try re-flashing JetPack.

Q: GStreamer pipeline errors?

A: Ensure JetPack ≥ 5.0. Run apt list --installed | grep nvarguscamerasrc to verify GStreamer plugins.

Q: How to switch cameras?

A: Change the sensor-id parameter: sensor_id=0 for first camera, sensor_id=1 for second.
