3. TECHNICAL BRIEF
The Camera module is connected to main board with 24pin Board to Board connector (AXK7L24227).
Its interface is dedicated camera interface port in MSM6250. The camera port supply 24MHz master
clock to camera module and receive 12MHz pixel clock (30fps), vertical sync signal, horizontal sync
signal, reset signal and 8bits data from camera module. The camera module is controlled by I2C port
from MSM6250.
