    Ce buzzer actif fonctionne bien mais il n'est pas plus puissant qu'un buzzer de base

    As said by "gabiel" the labels are wrong. Connect +voltage to the "-" connect the ground to the "S". You will hear a high pitched buzzer sound. It's probably possible to adjust the frequency by adjusting voltage or using a controlled sinus, but I haven't done that yet. I didn't use the middle pin, I don't know what it is used for. Using the buzzer for my Raspberry Pi project now and it works good!

    I bought this buzzer to install it on my racer 250 because i use ibus and betaflight. Adding a transistor and resistance you have a buzzer that serves you as lost model alarm and also indicates when you arm/disarm and when you change flight modes

    Ordine effettuato il 26 marzo 2014 e ricevuto oggi 06 maggio 2014 (41 giorni). La merce, una volta arrivata in Italia, era tracciabile come raccomandata internazionale sul sito delle Poste italiane. Il Prodotto, dopo averlo provato accuratamente, è perfetto sotto ogni punto di vista e sicuramente ne ordinerò altri in un prossimo futuro. è un ottimo venditore e vale la pena aspettare qualche giorno in più per fare acquisti molto vantaggiosi.

    Good speaker for your Arduino projects, but mine come with the labels wrong. See the attached image, labels are inverted from the one in the product description; just connect the cables reversed (Ground to "S" labeled pin and PWM to "-" labeled one).
