OV7670 CMOS Camera Module VGA

The OV7670 is the entry point for adding a camera to a microcontroller project without jumping straight to a full ESP32-CAM board: a bare VGA sensor outputting raw YUV, RGB or RAW pixel data that a host microcontroller captures and processes itself, rather than a self-contained camera-plus-processor module. That makes it a more hands-on integration - the host handles frame capture timing - but also a cheaper and more flexible one for projects building custom vision pipelines.

Configuration runs over SCCB, essentially an I2C variant, letting a project adjust exposure, white balance and other capture parameters in software rather than fixed hardware settings. At 30fps maximum and 60mW power draw, it suits low-power, moderate-frame-rate applications rather than high-speed video capture.

Common uses are basic robotics vision (line or object detection), simple surveillance prototypes, and STEM education projects introducing image capture and processing fundamentals.
