The Mini 5V Lost Buzzer with JST female plug offers a reliable, simple and compact way to add audible alerts to your devices. It is designed for low-voltage circuits and suits drones, RC vehicles and electronics projects.
It alerts you immediately if a signal is lost or the battery is low, and the plug-and-play JST connector makes integration hassle-free.
Because a lost model can be hard to find in grass or trees, a loud buzzer is one of the cheapest ways to improve your chances of recovering it.
Compact design: small enough to fit any project.
Audible alerts: a loud, clear sound when signal is lost or battery is low.
Easy installation: the JST female plug gives a quick, secure connection.
Low-voltage compatibility: operates at 5V.
Versatile: drones, RC vehicles, quadcopters and other devices.
A buzzer wired to a flight controller or receiver output is switched on by the controller when a condition occurs, for example when the radio signal is lost or the battery is low. The controller applies power to the buzzer, and the buzzer makes a loud tone that you can follow to find the model.
Most flight controller firmware lets you choose which events trigger the buzzer, such as arming, failsafe or low battery. Connect the buzzer to a 5V buzzer pad with the correct polarity and test it on the bench before flying.
Remember that many simple buzzers only work while the flight controller is powered. If the main battery is disconnected after a crash, a self-powered finder is more useful.
