Description
JHE42B 110 dB buzzer with LED
The JHE42B buzzer is a finder for FPV drones with its own battery. While you fly it works as the flight controller’s normal buzzer; if the drone’s battery comes off or runs flat after a crash, after 30 seconds it starts beeping at 110 dB and lights a white LED so you can find it.
It works with any flight controller running Betaflight or Cleanflight: just connect it to the buzzer pads. With the drone powered, the flight controller charges its battery, and a red LED shows that it is charging.
