The 1.3M Camera module is connected to main board(AXK7L26227) with Camera FPCB
(AXK8L26125). The VGA Camera module is connected to main board(AXK7L50227) with Camera &
LCD FPCB(AXK8L50125). 1.3M Camera module is connected to FPCB with 24-pin Board to Board
connector(14-5602-024-000-829 - 1.3M Camera). VGA Camera module is connected to FPCB with
20-pin Board to Board connector(AXK720145 - VGA Camera). Its interface is dedicated camera
interface port in Marita. The camera port supply 13MHz master clock to camera module and receive
17MHz pixel clock(15fps), vertical sync signal, horizontal sync signal, reset signal and 8bits YUV data
from camera module. The camera module is controlled by I2C port.
