The buzzers that are connected to the FC are the ones that make sound when you just feed them with power. I.e. the ones that have internal schematics to generate sound.

Buzzers from motherboards do not have such schematics and should be driven with external signal.
Feel like constantly chasing perfection. Once you think you almost got it, see how far you are really.

You can't get battery voltage telemetry from the IA-6B without either plugging in a voltage sensor or modifying the receiver itself.

Make sure the buzzer is an active buzzer and not a passive buzzer.
If it ain't broke, DON'T FIX IT!
