Compact USB camera module for machine vision

The Weinandianzi WN-G3822PX-KZB-170 integrates a 1/4.0-inch OV9712 CMOS sensor delivering a maximum resolution of 1280x720 at 30 frames per second. It connects via a high-speed USB 2.0 interface with a default 1.0 metre cable and uses a 4-pin 2.0 mm connector on the PCB. The module measures 53.5 mm by 12 mm by 4.8 mm with a 170 mm FPC, making it suitable for tight enclosures.

Thermals and power in typical operation

The sensor draws power directly from the USB 2.0 bus, so no external supply is required. An electronic rolling shutter and fixed-focus lens with a 3.4 mm focal length and F/2.8 aperture keep the design simple and silent. Dynamic range reaches up to 72 dB, and controllable parameters such as exposure and white balance can be adjusted in software without adding heat.

What the bundled cable

A 1.0 metre USB cable is included, enabling immediate plug-and-play use on Windows, Android, Linux and Mac OS without driver installation. The module outputs MJPEG at 1280x720, 640x480 and 320x240 all at 30 fps, while YUY2 is available at 5 fps for the two higher resolutions and 30 fps at 320x240. The 65-degree field of view and 650 IR filter suit general-purpose machine vision tasks.

Questions about this item

How do I mount the WN-G3822PX-KZB-170 and connect the 4-pin 2.0mm header to a USB port?

The module PCB measures 53.5×12×4.8 mm with a 170 mm FPC tail. Plug the 4-pin 2.0 mm connector into a matching header, then use the included 1.0 metre USB 2.0 cable to reach a host USB-A port; UVC makes it plug-and-play on Windows, Linux, Android or macOS.

What part of the OV9712 module is most likely to need replacement after long-term use?

The fixed-focus 4P+650IR lens (EFL 3.4 mm, F/2.8) and the 1.0 metre USB cable are the only moving or flexing parts; the rolling-shutter CMOS sensor and PCB have no serviceable components, so cable wear or lens damage would be the first failure points.

At what frame rate does the 1280×720 YUY2 stream become the bottleneck during continuous capture?

YUY2 at 1280×720 is limited to 5 FPS by the USB 2.0 bandwidth, while MJPEG sustains 30 FPS at the same resolution; sustained uncompressed capture will hit the 5 FPS ceiling first.
