BetaFPV 5V Active Buzzer for FPV Drones

BetaFPV 5V active buzzers for FPV drones, RC planes and helicopters. Wired to the flight controller's buzzer pads, they sound arming, low-battery and lost-model alarms, the beeps that help you find a quad in long grass after a crash.

Key features

• 85dB minimum sound output, measured at 10cm.
• Active buzzer: runs on 5V DC with its own oscillator, so the flight controller only switches it on and off.
• Two-terminal, continuous-tone element.
• Two pack options: six 9 x 5.5mm buzzers, or six each of 9 x 5.5mm and 12 x 9.5mm.
• 9 x 5.5mm size fits tight whoop and micro builds; the 12 x 9.5mm suits 5-inch and larger frames with more room.

Solder the leads to the BZ+ and BZ- pads on the flight controller, observing polarity, and enable the beeper in Betaflight or INAV to use it as a lost-model alarm. It has no battery of its own, so it falls silent once the flight pack is unplugged or ejected.
