I have a quadcopter on which I want to connect a servo, I bought a ppm to multiple PWM converter to connect on the flight controller PPM output, but I don't find how to tell betaflight to control the servo through the converter.

I tried to configure the servo in the servo tab but it does nothing.

    $\begingroup$ Why are you using a PPM to PWM converter? The "ppm" on the board is an input (unless remapped with resource mapping) and betaflight/inav do not output PPM. You want to connect your servo to a "motor" output and look into the servo mappings to those motor outputs $\endgroup$ Aug 17, 2021 at 16:14

    $\begingroup$ @BrydonGibson Ok, I understand better know, I think I can't do that with this FC even if there's several pins that are physically available there's no documentation. Thanks $\endgroup$

    $\begingroup$ Look into the "resource" CLI command in betaflight. You can use it to figure out mappings based on what the target developer has decided for this board. Effectively, it is the documentation $\endgroup$ Aug 18, 2021 at 14:14
