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.
