OV7670 Camera Module VGA 640×480 Image Sensor Board SCCB I2C Arduino

🔧 OV7670 Camera Module | AuscomTech

The OV7670 Camera Module is a compact VGA image sensor board designed for embedded imaging, DIY electronics, and microcontroller-based vision projects.

It uses the OV7670 single-chip camera sensor with built-in image processing features and supports multiple output formats including Raw RGB, RGB565/555/444, YUV, and YCbCr. Image quality parameters such as white balance, saturation, gamma, sharpness, and exposure can be configured through the SCCB control interface, which is compatible with I2C-style control.

This module is commonly used with Arduino-compatible development projects, custom image capture systems, robotics, and low-resolution machine vision applications where compact size and low operating voltage are important.
