1. Wiring.
（1）If only one servo is used, it can be directly connected to the s9 pad (no mapping required).
NOTE: The 5V BEC on F405v3 supports a maximum output of 5V 2A. Please ensure that the power consumption of the servos does not exceed the output of the flight controller BEC.
（2）If you need to use multiple servos, you can connect to the m5-m8 pad of FC and map it.
For example, three servos are needed, and the servos are connected to the three pads of s9, m5, and m6.
Please enter the following into the CLI:
resource MOTOR 5 none
resource MOTOR 6 none
resource SERVO 2 B00
resource SERVO 3 B01
save
2. Settings.
（1）Please check the firmware version of your flight controller.
If you are using betaflight 4.4 or above, please select the "SERVO" option during firmware flashing to enable servo functionality.
（2）Please enable SERVO_TILT on the Configuration page of the Betaflight configurator.
（3）Set the corresponding remote control channel on the Servo page.
（3）After the setting is complete, you can select: "Enable Live mode" to check whether the servo is rotating normally.

In the description, it was forgotten to mention that S9 connects to B15 because initially, it is NONE.
To enable the servo on S9, you need to enter the following code in CLI:
resource servo 1 B15saveHi guys, I've faced with some difficulties.
I`m trying to add 3 servos to my drone, I don`t have any problems with first one and second one. But the third one doesn't work at all.
I tried different options MOTOR 5-8, but they all worked only for 2 servos, the third one doesn't work at all.
