OV7670 VGA CMOS Camera Module – 640x480 Image Sensor
OV7670 VGA CMOS Camera Module – 640x480 Image Sensor
The OV7670 is a low-voltage CMOS image sensor that captures VGA (640x480) resolution images and video. It’s commonly used in embedded systems for real-time image capture, face detection, and simple computer vision tasks. With an integrated analog-to-digital converter and serial camera control bus (SCCB) interface, it’s easy to integrate with popular microcontrollers.

Compatibility
This module works with any microcontroller that has an 8-bit parallel interface and I2C for configuration. It’s commonly paired with Arduino (Uno, Mega via frame grabber libraries), ESP32, STM32, and Raspberry Pi Pico. Note that direct 8-bit parallel capture requires many GPIO pins or a dedicated camera interface; some platforms use FIFO buffer add-on boards to simplify reading.
Wiring Notes
Connect the 3.3V and GND pins to your microcontroller’s power supply. The SCCB control lines (SDA, SCL) are I2C-compatible; use 2.2k–4.7k pull-up resistors if not present. The 8 data pins (D0–D7) plus horizontal/vertical sync and pixel clock must be connected to free GPIOs. Due to high data rate, keep wires short and consider using a logic level converter if your MCU is 5V.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino Uno?
Yes, but capturing full VGA at 30 fps is challenging due to memory and speed limits. Use libraries like OV7670 or ArduinoCamera and consider a lower resolution or frame rate, or add a FIFO buffer board for smoother operation.
What’s the maximum frame rate for VGA?
The OV7670 supports up to 30 fps at VGA in standard modes, but actual throughput depends on your microcontroller’s ability to read data quickly enough.
Does it come with a lens?
Yes, the module includes a fixed-focus lens. You can manually adjust focus by rotating the lens barrel.
