Part 4.8: Camera Module Interface

Figure 4-8-1: CMOS camera interface Schematic

The development board includes an 18-pin CMOS camera interface that

can be connected to the OV7670 camera module and the OV5640 camera
module for video capture. After acquisition, the monitor can be connected via
HDMI or VGA interface for display. OV7670, 30W pixels, output resolution is
640*480; OV5640, 500W pixels, output resolution up to 2592*1944. Regarding
the choice of camera, users can purchase according to actual needs.
