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:

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.
