Part 4.8: Camera Module Interface 

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.
