OV7670 VGA Camera Module

WORKING PRINCIPLE: The OV7670 VGA Camera Module is a low-cost CMOS image sensor with an onboard DSP that captures 640×480 (“VGA”) images at up to 30 fps (0.3MP). Light entering the lens is converted to digital signals by the CMOS sensor, and the DSP can pre-process the image data before output, handling tasks such as color correction, de-noising, edge enhancement, and flicker reduction. The module supports Vario Pixel sub-sampling for flexible resolution adjustment and auto image control functions for consistent imaging quality.
MODULE STRUCTURE: The module features an OV7670 CMOS sensor mounted on a black FR-4 PCB with a magnesium alloy lens seat and all-glass lenses. The focal length of the lens is 3.6 mm. The module includes a 2×10 0.1″ output connector for easy integration with prototype boards and microcontrollers. It operates on 3.3V DC and is compatible with 8/16/32-bit MCU interfaces.
PIN CONFIGURATION: 1 – 3V3 (Power), 2 – GND (Ground), 3 – SIOC, 4 – SIOD, 5 – VSYNC, 6 – HREF, 7 – PCLK, 8 – XCLK, 9 – D7, 10 – D6, 11 – D5, 12 – D4, 13 – D3, 14 – D2, 15 – D1, 16 – D0, 17 – RESET, 18 – PWDN
INTERFACE CONNECTION: Uses the standard SCCB interface (compatible with I2C) for image control and configuration. Provides easy connectivity to microcontrollers and prototype boards via the 2×10 header.
OUTPUT FUNCTION: Captures VGA (640×480) images and supports real-time image pre-processing, including color saturation, hue, gamma, sharpness adjustment, anti-blooming, lens shading correction, edge enhancement, de-noising, flicker auto-detection, and auto white balance.
OPERATING VOLTAGE: 3.3V DC
SIGNAL CONDITIONING: Built-in ISP performs noise reduction, defect correction, image scaling, and auto adjustments for color, edge, and brightness. Low-power sleep mode consumes <20 μA.
