OV7670 Serial camera module

The OV7670 image sensor is a small size, low voltage, single-chip VGA camera and CMOS image processor for all functions.

It provides full-frame, sub-sampled or windowed 8-bit images in various formats, controlled through the Serial Camera Control Bus (SCCB) interface.
The camera module is powered from a single +3.3V power supply, and external clock source for camera module XCLK pin. The OV7670 camera module has built-in on-board LDO regulator only requires single 3.3V power and can be used in Arduino, STM32, Chipkit, ARM, DSP, FPGA and etc.
