iFlight 2pcs 5V Buzzer Alarm Super Loud FPV Buzzer Support F3 F4 F7 Flight Controller for FPV Racing Drone RC Quadcopter

Great tail light and buzzer. Makes my quad look killer. Crisp and loud beep, easy to install (the buzzer and LEDs share the same +5v input just sent the single white wire to the FC's - buzzer solder pad). The lights move with throttle as per betaflight's LED configuration tab but I need more experience in order to reprogram them.

These are very loud. And the way I had them set up they beeped whenever the motors did. And the startup tones were WAY too loud. I think that can be disabled in beta flight. I also had it beeping when battery started getting low which i liked. I could hear them louder than my 5" motors/props. Also has 4 programmable leds. One negative is I couldn't really see any great ways to mount it. As there are exposed pads and components everywhere. I ended up covering everything exposed with very sticky electrical tape and zip tieing it between the standoffs. Another thing is I couldn't find how much amps this pulls to see if my FC could power it along with everything else. All in all I would recommend it if you can disable those startup tones.

The media could not be loaded. 5 V goes to a 5 V , buzz negative goes to buzz negative , LED goes to the LED tab , ground goes to ground , perfect! also, is totally controllable in beta flight

Very bright LED's and the beeper is VERY loud. Easy to solder, the mounting holes are very convenient to just ziptie them right to the standoffs... nice thick wires to use come with them.... I have one one my drone that stil lworks perfectly, and have the other as a spare.Programmable the LED's do all the different colors I have mine to have the bottom two lights blue and the top two red when disarmed and the top two turn blue making them all blue when armed.

If they'd tell the truth about its sound output, that'd be nice. Yes, it's louder than the standard dime-store active and passive buzzers that come in the "get started" kits, but not my much."110dba" is a completely insane claim.No instructions for LED programming, either.Unsatisfactory, but I need something for my demo project, and I don't have time to return.

I like these kinda things for my quads, makes it look better and helps if i loose it for when I dont have the 32 bit ESC's, one thing il say though is that I wish it came with pre-installed wires and then have something over the pads because lots of people put these on or close to carbon fiber which is conductive so im pretty sure thats not the ideal situation but mine works great and its pretty loud too

Great LED and Buzzer all in one. Easy to install and control.

Installed on iFlight TurboBee 120RS. Works perfect after CLI command noted bellow. Very loud, customizable bright LEDs in Betaflight. Maybe little overkill for 2.5" but I'm no longer afraid to fly aggressive around tall grass / shrubs. If crashed - I WILL find quad quickly. For price - it's a steal!!!For some boards you have to go to cli and typeset beeper_inversion = ONset beeper_od = OFFsave
