The 640x480 CMOS Camera Module delivers VGA resolution imaging for electronics and embedded projects. Compact and lightweight, it’s widely used in Arduino projects, Raspberry Pi vision systems, security prototypes, and DIY electronics. This module provides real-time image capture at 640×480 pixels, making it suitable for basic computer vision, robotics, and surveillance applications. In Bangladesh, it’s a popular choice among students, researchers, and hobbyists who need an affordable yet practical imaging solution for experimentation.
The OV7670 is a low-voltage CMOS image sensor that integrates the full functionality of a single-chip VGA camera and image processor in a compact package. It outputs 8-bit images in full-frame, sub-sampled, or windowed formats, all configurable via the Serial Camera Control Bus (SCCB) interface.
The sensor’s image array supports up to 30 frames per second (fps) at VGA resolution, making it a versatile choice for embedded vision and imaging projects.
