Here’s another 5V piezo buzzer, but this one is different from the rest in that it’s compatible with both PWM receivers and with most racing drone flight controllers. When used with a flight controller, it can be setup as a low voltage alarm, lost model alarm and it can also be configured to provide status alerts like ‘no rx signal’ and other warnings*. If you use it with a traditional PWM receiver, simply connect it an auxiliary channel and activate it with a switch on your transmitter. If your radio supports failsafe, you can set it up so the buzzer will activate if your drone flies out of range.
The buzzer is tiny and only weighs 2g, so it could be used on small racing drones through to biggest heavy lifting octocopters.
