    Good buzzers, with sticker on so you can safely clean the pcb without damaging the buzzer.

    The buzzer works, it's exactly what I needed.

    Finally found a buzzer that works on DC current! I am not an electronics expert in any way, shape or form so I have spent a bit of money in the past on buzzers that I wanted to use on projects, only to realize that I needed a 5 Volt AC current to run them. Making a DC to AC converter is beyond my capabilities and, in any case, I couldn't find a circuit diagram for one. This buzzer is active, so it has its own built-in converter and will work beautifully from a 5V DC power supply or battery, with

    Бузеры рабочие. Все как в описании. Провел небольшой тест, измерил приложением в телефоне уровень громкости, одной и двух пищалок. Вывод две пищалки соединенные в параллель не дают в два раза больше громкости.

    Required when you don't want to lose your quad. Betaflight also gives you multiple options about when the buzzer has to beep. It is loud enough, and having 5 is good to have some spares.

    Ces buzzers sont minuscules : ~9mm de hauteur pour ~11mm de diamètre. Et pourtant le son qu'ils produisent est très fort et clair (quand on n'oublie pas de retirer le papier autocollant protecteur...)

    Cheap and easy to install. The longer pin is the positive. The buzzer is not self-powered (will not work if the battery is unplugged in a crash), and not very loud. But does the job in most cases. I used a pair of spare-wires (cut off the ESCs) to plug the buzzer on the FC. Attached it with a zip tie and some piece of foam tape on the frame.

    Batch of 5 small buzzers with continous beep. They are 2 wires only, so they need to be connected to drivers that manage the power to the device. Connected to racers with F3 flight controller can be used both to give low battery warning or to be used to locate the quad in case of crash in high grass or other hidden places.
