Camera Module OV7670

3V3 —– Input power supply voltage (3.3 is recommended, 5V is also possible, but not recommended)
GDN —– Grounding point
SIO_C — SCCB interface control clock (note: some low-level single-chip microcomputers require pull-up control, similar to the I2C interface)
SIO_D — The serial data input (output) end of the SCCB interface (Note: some low-level microcontrollers require pull-up control, similar to I2C interface)
VSYNC — frame synchronization signal (output signal)
HREF —- line synchronization signal (output signal)
PCLK —- pixel clock (output signal)
D0-D7 — Data port (output signal)
RESTE — Reset port (pull normally in normal use)
PWDN —- Power consumption selection mode (pull down normally)

The OV7670 image sensor has a small size and low operating voltage, and provides all the functions of a single-chip VGA camera and image processor. Through SCCB bus control, it can output 8-bit resolution data of various resolutions in the form of whole frame, sub-sampling, and window taking. The VGA image of this product is up to 30 frames per second. Users can fully control the image quality, data format and transmission method. All image processing functions including gamma curve, white balance, saturation, chroma, etc. can be programmed through the SCCB interface.
