Introduction

Some compact products cannot easily accommodate a conventional rectangular camera PCB. In these designs, the shape of the camera board can be just as important as resolution or interface.

This VGA USB camera module uses a compact round PCB structure, providing a practical integration direction for handheld products, compact inspection devices and other equipment with limited internal mounting space.

The standard configuration supports 640×480 video at up to 30fps through USB 2.0, with UVC compatibility and YUY2 output. A 90° lens provides moderate scene coverage without moving into an ultra-wide optical direction.

Applications in Real Devices

Handheld Imaging Devices

Portable devices often have limited space around the camera position.

The compact round PCB can fit mechanical structures where a conventional square board would occupy unnecessary corner space.

Document Capture Equipment

For document or desktop capture devices, VGA video can provide a lightweight image source when the task does not require high-resolution text recognition.

The 90° viewing direction also provides relatively broad scene coverage from a fixed mounting position.

Compact Inspection Instruments

Inspection devices may need a small camera board integrated close to the viewing area.

The round structure and USB interface provide a practical option when mechanical simplicity and host integration are more important than high-resolution processing.

Embedded USB Viewing Systems

Products using a PC or embedded USB host can integrate the camera through a standard USB video architecture instead of developing a raw sensor interface.

The specification identifies USB 2.0 and UVC compatibility for this module.

Project Evaluation Guide

Consider This Model When

A round or compact camera PCB fits the enclosure better than a rectangular board.
VGA resolution is sufficient.
640×480 at 30fps meets the video requirement.
USB 2.0 integration is preferred.
UVC compatibility is important.
A 90° lens provides suitable scene coverage.
Low USB-side power consumption is useful.
YUY2 output matches the host workflow.

Confirm Before Sampling

Actual available camera diameter.
Required working distance.
Required scene width.
Whether 90° FOV provides enough coverage.
Whether VGA contains enough target detail.
Host operating system and UVC support.
USB cable and connector requirements.
Lens height available inside the enclosure.
Whether the standard focus setup matches the target distance.

Choosing This Model Within the USB Camera Module Series

This model represents the round-PCB VGA USB direction within the compact USB camera range.

Choose it when the mechanical structure benefits from a circular camera board and the application only requires VGA-level video.

Compared with rectangular USB modules such as SF302D or SF-C0319USB-WH03, the main difference is not simply resolution—it is the mechanical integration direction. The round PCB can be more suitable for compact housings where board corners become a space constraint.

SF302D
Consider this model when a 30×25mm rectangular PCB and multiple lens options from 62° to 150° are more useful than a round board structure.

SF-C0319USB-WH03 V1.0
Consider this model when a compact 14×25mm rectangular PCB fits the enclosure better than a round camera board.

SincereFirst Customization

Lens and Viewing Angle

Lens configuration can be evaluated according to the required scene width, target size and camera installation distance.

Focus and Working Distance

The focus setup can be reviewed according to the real operating distance when the standard configuration does not match the final device.

Round PCB and Mechanical Structure

PCB diameter, mounting position and lens height can be evaluated according to the available enclosure space and product structure.

USB and Host Integration

USB cable, connector direction, UVC compatibility and image parameters can be reviewed according to the target host and application software.

Final configuration should be validated with the actual host platform, enclosure, optics, software, and lighting environment before sampling.

FAQ

Why choose a round PCB camera instead of a square module?

A circular PCB can make better use of space inside round or cylindrical housings where the corners of a square board would interfere with the enclosure.

The correct choice should therefore start with the mechanical layout rather than PCB area alone.

Is VGA resolution enough for inspection?

It depends on the smallest feature that must remain visible.

For general viewing, positioning or basic inspection, VGA may be sufficient. For fine defect detection or text recognition, higher resolution may be required.

What does the 90° lens mean for target size?

A 90° FOV provides relatively broad scene coverage.

If the target needs to occupy more pixels in the VGA image, a narrower viewing angle may be more appropriate.

Does UVC mean the camera can work with every USB host?

No.

UVC simplifies compatibility, but the host operating system, USB implementation, application software and power conditions should still be confirmed.

Can the lens configuration be changed?

The product specification shows different physical lens configurations in its product images, including shorter and taller lens structures, indicating that optical configuration can be adapted according to the project. Exact lens parameters should be confirmed before sampling.

What should be provided before selecting this module?

Provide the available camera diameter, enclosure depth, working distance, target size, required FOV and host USB requirements.

Request Project Evaluation

If your device needs a compact round-PCB USB camera, share the available mounting diameter, lens-height limit, working distance, required scene coverage and USB host conditions.

SincereFirst can help evaluate whether this VGA 90° configuration fits the device or whether a different optical setup is more appropriate.
