Product Introduction
OV7670 is a type of CMOS image sensor, commonly used in digital camera modules. It can achieve image data caching and storage through the FIFO module, thereby reducing the burden on the main processor.
OV7670 Feature
- The working voltage range is wide, ranging from 2.5V to 13.5V.
- Dual channel output, capable of driving two DC motors at the same time.
- The maximum continuous driving current for each channel is 1.2A (peak 3.2A).
- The module is internally equipped with a low voltage detection and overheat protection circuit.
- In the standby mode, the internal circuit will be disconnected to reduce power consumption.
- The PWM frequency can be set within a wide range (1kHz – 100kHz).
- Small in size (24mm × 15mm), it is convenient for installation.

OV7670 Usage Instructions
- Image quality problem: If you find the image quality is poor, you can try adjusting the camera parameters, such as increasing brightness and contrast, or using image post-processing algorithms for image enhancement.
- Frame rate problem: If you need to increase the frame rate, you can reduce the resolution or decrease the image processing operations to achieve this.
- Data transmission problem: If there are errors or losses in data transmission, you can check if the hardware connection is correct, if the clock frequency is appropriate, or add data verification measures to improve the reliability of data transmission.
- If the picture is unclear, please rotate the small lens, and you can adjust the focal length.
- Compared to other sensors, CMOS cameras are more challenging as they involve a lot of knowledge. Please do more evaluation and research before purchasing and using them, and make a decision accordingly!
OV7670 Application
The OV7670 camera module can effectively alleviate the data processing pressure of the MCU, enabling smooth image acquisition and transmission. It can be applied in various fields such as small experiments, product development, production needs, instrument and metering, and intelligent manufacturing, and is particularly suitable for embedded development scenarios with limited resources.
