A separate GPS, switch, and buzzer are connected to the Pixhawk 4.
But the buzzer doesn’t work properly.
The sound is not very loud, but very low. (To the extent that you can’t hear it at all when flying)
I can’t find a solution.
I’m looking at the possibility that the voltage is mismatched.
But I am not confident.
If anyone can help me a little, I would be very grateful.
Thanks for taking the time for any advice.
