SF-C0310USB-D3.9-PLUS-D9
SINCEREFIRST
This 3.9mm ultra-compact USB 2.0 endoscope camera module, with PCB board supports the UVC protocol. Featuring a standard USB interface and a diameter of just 3.9mm, it can access extremely narrow gaps or micro-pore spaces inaccessible to traditional cameras. It utilizes the device's existing USB port directly without requiring complex adapter boards. With a diameter of just 3.9mm, it can penetrate extremely narrow gaps or micro-pore spaces inaccessible to conventional cameras. Utilizing a standard USB interface, it requires no complex adapter boards and directly leverages the device's existing USB port for power supply and data transmission. The module features a steel shell with IP67 dust and water resistance. Its standardized PCB substrate employs industry-standard dimensions and layout, allowing engineers to easily reserve space during host motherboard design and reduce development complexity. Compatible with USB 2.0 UVC protocol, it automatically identifies as a camera when plugged into computers, Android boxes, or Linux development boards—no manual driver installation required. It offers seamless compatibility with mainstream operating systems including Windows, macOS, Linux, and Android, significantly shortening software debugging cycles. Supporting dual-format output (YUV and MJPEG), users can switch between formats via software to achieve dual functionality with a single device. This miniature visual imaging component is specifically engineered for applications such as endoscopes, pipeline inspection, micro-robots, medical catheters, and internal earphone housing environments. |  |
Product Advantage ◢
1.Close-Range Imaging: Designed specifically for close-proximity endoscopic applications with a depth of field of 5mm to 50mm. The integrated 120° ultra-wide-angle lens allows a single module to cover the inspection field of view within micro-spaces effectively.
2.Clear Imaging in Low-Light Conditions: Equipped with 4 high-brightness white LEDs. In environments with no ambient light (0 lux), activating the LEDs enables clear image capture.
3.Plug-and-Play Functionality: Utilizes a standard USB 2.0 interface, ensuring plug-and-play operation without complex driver adaptation across various host devices.
4.Wide Temperature Stability: Operates reliably within an ambient temperature range of -20°C to 70°C, with stable image quality maintained between 0°C and 50°C. This makes it adaptable to demanding industrial environments, outdoor inspections, and other scenarios with temperature variations.
1.Industrial Micro-Pipe Inspection: Suitable for inspecting the internal condition of ultra-small-diameter pipes such as thin water pipes, air lines, and oil tubes. It can penetrate micro-spaces inaccessible to conventional inspection equipment.
2.Precision Instrument & Electronic Component Inspection: Enables internal cavity examination of micro-mechanical parts, electronic chips, and precision instruments to identify internal faults or wear issues.
3.Automotive Component Inspection: Facilitates internal viewing of small engine passages, precision fittings, and confined cavities within vehicles, allowing assessment without component disassembly.
4.Basic Medical / Laboratory Micro-Cavity Observation: Applicable for non-invasive observation of small cavities and detailed viewing of miniature laboratory components and specimens.

FAQ ◢
1. Does the module's Micro USB-5P interface support hot-swapping? What is the standard for the number of insertion/removal cycles?
The module's Micro USB-5P interface is designed to meet industrial standards and supports hot-swapping operations. The number of insertion/removal cycles complies with USB industrial standards, meeting the demands of frequent insertion/removal in typical application scenarios.
2. Why do some modules differ several times in price?
The difference is due to sensor brands (such as SONY IMX series vs domestic), optical lens groups (aspherical lenses cost more), medical certification (such as FDA process takes 2-3 years) and other factors.
3. What does an endoscope camera module see?
A4: The endoscopic camera module captures detailed images and video of narrow internal structures and is typically used in medical, industrial or research Settings. In medical use, it is inserted into the body through slender tubes, capable of capturing high-definition images in small or hard-to-reach areas. The lens of an endoscope is usually equipped with a light source to provide a clear view in a dark environment. The device can record and transmit images in real time to help doctors look at organs, tissues and other internal structures to identify lesions, inflammation or other health problems. It can help visualize the stomach, intestines, bronchus, ear canal, nasal cavity, esophagus, bladder, prostate, vagina and other organs, allowing diagnosis and monitoring of conditions such as tumors, infections or blockages. The abnormalities of tissues and blood vessels can be seen in real time. In industrial Settings, it can inspect areas of machinery, plumbing or infrastructure that are difficult to see directly with the naked eye, highlighting wear, corrosion or blockage.
4. Regarding imaging clarity: Can it focus at an ultra-close distance of 5mm? Can it clearly show minute scratches?
The module's depth of field ranges from 5–50mm, with a minimum working distance of 5mm. At this distance, it clearly reveals surface textures of inspected objects. Combined with a 120° ultra-wide field of view, a single image captures a circular area approximately 10mm in diameter (at 5mm working distance), sufficient for clearly identifying minute details such as scratches, burrs, and foreign particles. The image sensor size is 1/18 inch, with pixel dimensions and resolution optimized for macro imaging scenarios.
5. Regarding Interface Compatibility: Does the USB 2.0 interface support mobile phones or embedded platforms?
The module employs a standard USB 2.0 interface supporting the UVC protocol, enabling plug-and-play functionality on mainstream operating systems including Windows, Linux, and Android. Connecting to a mobile phone requires an OTG adapter cable and confirmation that the phone supports external UVC devices. Connecting to embedded platforms (e.g., Raspberry Pi, Jetson Nano) enables direct recognition without additional drivers. Pin definitions are standardized as VBUS, D+, D-, and GND, supporting integrated 5V power supply and data transmission for seamless integration into various terminal devices.
