Description
110 dB buzzer with LEDs for FPV drones
This 110 dB buzzer connects to your flight controller and beeps to warn of low battery, on arming, or when you trigger it from your radio to find the drone after a crash. It is very compact, just 14 mm tall, so it fits low-profile frames.
It also has 4 programmable WS2812 LEDs that you can control from Betaflight to change colours or show the drone’s status. It works with F3, F4 and F7 flight controllers and runs on 5 V.
