OV7670 VGA Camera 300KP Module — single-chip image sensor with SCCB interface, 8-bit data output, and up to 30 fps at VGA resolution. Compact and low-voltage design ideal for Arduino and embedded vision projects.

 

The OV7670 is a compact VGA camera module by OmniVision that integrates a 300KP image sensor and image processor on a single chip. Operating at low voltage, it communicates via the SCCB bus (Serial Camera Control Bus, compatible with I²C) and outputs 8-bit image data, making it a popular choice for embedded vision applications with microcontrollers and single-board computers.

Key Features

  • 300KP VGA Resolution: Captures images at VGA (640×480) resolution → sufficient for object detection, video streaming, and machine vision prototypes
  • Up to 30 fps: Full-frame VGA output at 30 frames per second → smooth real-time video capture
  • SCCB Interface Control: Full programmability over image quality settings → adjust gamma, white balance, saturation, and chroma via software
  • 8-bit Parallel Data Output: Standard parallel interface for image data → compatible with microcontrollers that support parallel camera interfaces
  • Flexible Output Modes: Supports full frame, sub-sampled, and windowed output → reduce data load by capturing only the region of interest
  • Compact Form Factor: Small PCB module → easy to integrate into space-constrained enclosures and prototypes
  • Low Operating Voltage: Designed for low-power embedded systems → suitable for battery-powered and portable devices

Wiring note: The OV7670 operates at 3.3V. When connecting to a 5V Arduino, use a logic level shifter on the SCCB (SCL/SDA) and data lines to avoid damaging the sensor. The XCLK signal must be provided by the host MCU (typically 8–24 MHz).

Compatibility

  • Arduino UNO / Mega: Compatible via logic level shifting (5V → 3.3V required on data and SCCB lines). The Mega is preferred due to more available I/O pins for the parallel data bus.
  • ESP32: Natively 3.3V — direct connection supported. ESP32-CAM uses the same OV7670 sensor family.
  • STM32 / ARM Cortex-M: Well-supported with hardware DCMI (Digital Camera Interface) peripherals for efficient parallel data capture.
  • Raspberry Pi: Can be interfaced via GPIO with software bit-banging or a dedicated camera adapter.

Typical Applications

  • DIY security cameras: Build a low-cost surveillance or motion-detection camera with an Arduino Mega or ESP32.
  • Machine vision prototypes: Capture and process images for color detection, shape recognition, or barcode reading in maker projects.
  • Robotics: Add visual awareness to your robot — line following, obstacle detection, or target tracking.
  • Educational projects: Learn image sensor interfacing, parallel bus communication, and real-time image processing concepts.
  • IoT image capture: Integrate with an ESP32 for wireless image transmission and cloud upload applications.

FAQ

Q: Can I use the OV7670 directly with a 5V Arduino UNO?
A: Not directly — the OV7670 is a 3.3V device. You must use a logic level shifter on all signal lines (SCCB, XCLK, and D0–D7) to prevent damage to the sensor.

Q: Does the OV7670 module include a FIFO buffer?
A: This standard OV7670 module does not include a FIFO buffer. A separate OV7670+FIFO variant exists if you need buffered image capture without tight timing requirements on the MCU side.

⚠ Note: This module operates at 3.3V only. Applying 5V directly to the signal or power pins will permanently damage the sensor. Always verify your voltage levels before connecting.
