Customer Questions & Answers
What advantages does the OV7670 sensor offer over other camera modules for Arduino in the same price range?
The OV7670 stands out for its low cost, straightforward integration with Arduino platforms and its ability to capture images at VGA resolution (640x480 pixels) at acceptable speeds (up to 30 fps), while keeping power consumption low (60 mW at 15 fps). However, it lacks internal FIFO memory, which means more complex processing compared with modules such as the OV2640, although these are usually more expensive.
What are the module dimensions and what exactly is included in the box?
The module generally measures 28 mm x 23 mm x 21 mm (width x length x height, including the lens); approximate weight is 8 g. The box includes the camera module with integrated lens and soldered pins, with no cables or additional items. No printed manual is supplied.
What connections or voltage does it require to operate correctly with Arduino?
The module requires a 2.5V to 3.0V supply; the data pins typically operate at 3.3V and it is essential not to power it directly with 5V, as this could damage it. Control is via the SCCB interface compatible with I2C. Level shifters are recommended when connecting to Arduino boards with 5V logic.
How does the lack of FIFO memory affect performance and image processing with basic microcontrollers?
As it does not include FIFO memory, the OV7670 outputs data in real time; this forces the microcontroller (such as an Arduino Uno) to read and process each pixel on the fly, significantly limiting capture speed and increasing software complexity. To obtain full images, it is advisable to use more powerful microcontrollers or add external memory.
What temperature range and environmental conditions can the module withstand during continuous operation?
The OV7670 module operates safely between -30°C and +70°C. It is recommended to avoid prolonged exposure to high humidity or dust without additional protection, as the lens is not sealed. Standard mechanical tolerances do not guarantee resistance to water or heavy impacts.
Is the Arduino OV7670 camera module compatible with standard Arduino boards?
Yes, the module works with Arduino boards that support voltages from 2.5V to 3V and can handle SCCB and I2C interfaces for communication.
What is the maximum resolution this module offers?
The module offers a maximum VGA resolution of 640x480 pixels at 30fps.
What image output formats does the module support?
It supports 8-bit output formats: YUV/YCbCr 4:2:2, RGB 565/555/444 and GRB 4:2:2.
Where can I find documentation and usage examples?
You can find more information and examples on the official website https://www.arducam.com.
What is the operating temperature range for the module?
The module operates in a temperature range of -30°C to +70°C, suitable for various environments.
