If the user designs to use the CAMERA module with autofocus function, please note that
the I2C of the module cannot be directly connected to the AF device. The I2C of the AF device
should be connected to the driver chip of CAMERA, and the correct connection is as follows:
Figure 4.18： Correct CAMERA connection diagram
The MIPI interface has a high rate. The user should control the impedance by 100 ohms
during the routing. Please pay attention to the length of the trace. It is not recommended to add
a small capacitor on the MIPI signal line. This may affect the rising edge of the MIPI data. This
in turn causes the MIPI data to be invalid.
