    I wanted a buzzer for a Raspberry Pi project and this seemed to be suitable, with a good price. The module has three pins, but only two are needed. Connect "S" to a Pi GPIO pin. Connect "-" to Pi GND. This is an 'active' module, so it makes a noise when it is turned on, i.e. it is not necessary a... Read more

    Using the buzzer is very easy: it can be connected directly to a GPIO pin of Raspberry Pi and can work without PWM, only by switching on/off.

    When I got the buzzer I thought is would only have a binary on and off and would just buzz. It does do that, but if you pulse current through it you can get any tone. Maybe it's just me, but I didn't expect that. When I was soldering this to my board, I held the iron to the module for a long time... Read more

    This a very nice little buzzer. Its output audio level is quite high. It is very easy to integrate in your Arduino projects. Even if the quality is not bad, I think that the symbols on the board are inverted... I've read the other comments saying that "S" is to be connected to and to my... Read more

    Buzzer itself works as it's supposed to. And I like black PCB :) I couldn't get this thing to work the way pins are marked, then I figured out that GND should go to pin marked as "S", and Arduino's PWM signal goes to pin that is marked as "-". Works with Arduino, just reverse pins as described in... Read more

    Its a solid construction, came with a lot of protections in a sealed plastic bag, works really good on my arduino mega, works with computer output... and its a quite loud :D dont have any datasheet... I dont know for what is the center pin (as it have 3 pins). Its a small buzzer, perfect for any... Read more

    It seems to work the way it should. Simple to install and use! Great price! The pin mapping is something I'm a little puzzled about; at first I couldn't get it working, but after a closer look at the connections it seems easier to connect GND to what is "S" on the buzzer and to a PWM on...
