1. Start with your buyer requirements

Before you compare figures, write down what your project actually needs:

• Host interface and OS: Which operating systems must the camera run on, and can they use a standard UVC driver?
• Image format and resolution: Does your application need a wide aspect ratio, a square frame, or a specific resolution at a specific frame rate?
• Field of view and focus: How far is the subject from the camera, and does the subject distance change?
• Power budget: How much current can the host USB port or your enclosure supply?
• Environment: What temperatures will the device face during operation, storage and transport?

The sections below compare these needs with the published MY-USB-2-4M898A V2 specifications.

2. Interface and system compatibility

Selection check: The published compatibility list covers Windows XP through Windows 10, plus Linux or other operating systems with a UVC driver. If your product targets an OS that is not on this list, validate it on your own hardware first. The source material does not cover other platforms. The published VID/PID helps if your software has to identify the device.

3. Sensor and image quality figures

Selection check: The maximum effective pixel array is 3040×1520, which is a wide 2:1 frame. If your application needs a different aspect ratio, see the resolution modes below. Use the SNR and dynamic range figures to compare the module against the requirements in your own specification. The source does not include any low-light or high-contrast test results, so test the module in your real lighting conditions.

4. Lens, field of view and focus

Selection check: The module uses a fixed-focus lens with a 90±3° diagonal field of view. It is most likely to suit applications where the subject stays in a fairly consistent working range. If your application needs autofocus or optical zoom, this configuration is not suitable. The 650NM IR filter matters if you plan to use infrared illumination. Confirm whether this filter suits your lighting design before you commit.

5. Output formats, resolutions and frame rates

Published data formats: MJPG and YUV.

Selection check: Three of the listed modes run at 30fps: 3040×1520, 2432×1216 and 1920×960. The 1520×1520 square mode is listed at 5fps, and 2688×1520 is listed at 1fps. These two modes are therefore poor candidates for smooth live video. The source does not say which data format (MJPG or YUV) applies to each resolution and frame rate. Over a USB 2.0 link, confirm with the supplier which format delivers the mode you need.

6. Power and operating environment

Selection check: The module is powered over USB at 5V, with a published maximum working current of 250mA. Compare this with the current available on your host port. The published working temperature range is 0℃ to +50℃. If your device will run below freezing or above 50℃, such as in some outdoor or unconditioned installations, this specification does not cover that use. Storage and transport conditions should stay within -20℃ to +70℃.

When the MY-USB-2-4M898A V2 may not apply

Based on the published specifications, look at other options if your project needs any of the following:

• Autofocus or variable focus
• An interface other than USB 2.0
• Operation outside 0℃ to +50℃
• Square-format or 2688×1520 output at video frame rates (these modes are listed at 5fps and 1fps)
• Officially listed support for operating systems outside the published compatibility list

Questions to confirm with the supplier

The published material does not cover the following points. Raise them during your enquiry:

• Pricing, MOQ, lead time and sample availability
• Product certifications and compliance documents for your target market
• Which data format applies to each resolution and frame-rate mode
• Focus distance range, mechanical drawings and cable or connector details
• Customization options for your project

Summary

The MY-USB-2-4M898A V2 is a fixed-focus USB 2.0 CMOS camera module. It has a 3040×1520 maximum effective pixel array, a 90±3° diagonal FOV, MJPG and YUV output, and UVC-based compatibility with Linux and other operating systems. It is a reasonable candidate if your project runs on the listed operating systems, works with fixed focus, operates within 0℃ to +50℃ and uses one of the 30fps modes. For anything else, check with Shenzhen Minyou Digital Technology Co.,Ltd and test samples in your own application first.
