How to use servos with F7V3/F405V3/F405V4 in iNav
How to use servos with the F7V3/F405V3/F405V4 flight controllers in iNav (using the F405 V3 as an example)
1，Wiring.
Please connect the servo to the M5–M8 pads for use.
Please note that the 5V BEC on the flight controller supports a maximum output of 5V 2A. Make sure the servo’s power consumption does not exceed the BEC output.
2，Setup.
（1）You need to flash the INAV firmware (the default Betaflight firmware does not support servo usage).
（2）Open the Mixer tab in INAV.
（3）Select "Add new Mixer Rule" (add as many as needed, up to a maximum of 4).
（4）If you see "Servo 1" under Output Mapping, it means the servo has been successfully added.
（5）Set the channel to control the servo.
3，Open the Output page to check if the servo is working.
（1）Enable motor and servo outputs.
（2）Enable Live mode to check if the servo is working properly.
After completing the above settings, you can control the servo movement.
