I have put together a Quad X Drone and I want to add a drop servo. I cant seem to figure out how to wire. I have a Matek 405 SE FC to which I have attached a Matek compass, LED lights, Crossfire nano receiver and  4 in one ESC. I am using INAV software, Ver 2.6.  Although I have not put it in the air, every thing appears to work. Is it possible to add servo to this F.C.  I am using the led output for LED lights. Can I use the buzzer output for a servo hook up. ie. G,V, buzzer out for signal . Also, I have UART available. How do I activate the servo set up. I have a switch set up for channel 8.

I was able to do it in betaflight (mamba 405 stack)by remapping the led pad.. I also added a “facing down” camera on a momentary switch...
I’ve heard I nave is more “servo friendly”.. wish I could help

If you go to INav config output tab, you will see what servo outputs are available to you. Unlike BF, you will not be able to remap anything. Can you post a screen shot of the output tab?

I got a brilliant glare from the "Light Bulb" and oddly enough everything worked out. Its easy when one knows how. Thanks for your time
