How to Connect the Buzzer to Flight Controllers that features “Buzzer+” “Buzzer-” Soldering Pads?

How to Connect the Buzzer to EZ F411 AIO and Other Flight Controllers that don’t Feature Buzzer Pads？

Step 1. Firstly, please solder the buzzer’s signal wire ( blue wire) to any available/free port on the flight controller.
For example, RX1 is mostly the available port on the EZ AIO, so you can connect the
FC RX1 with the Buzzer Signal Wire (White Wire), FC 5V–Buzzer 3V-5V (Red Wire), FC GND–Buzzer GND (Black Wire)

Step 2. In Betaflight,  Enter “resource” in the CLI to find out the pin number corresponding to the port.
For example, pin number on the EZ corresponding to RX1 is A10.

Step3 . Free the available port in the CLI and then set the corresponding pin as beeper, finally enter “save” in the CLI
For example, on the EZ AIO board, in the CLI, enter “resource serial_RX 1 NONE” , and then enter “resource beeper 1 A10”. Finally enter “save” and you are done.
