    These buzzers keeps chirping, I spent an entire evening trying to understand why, but at some point after trying a few of them I came to realize they ar not up to their price...

    Handy little module

    Used these buzzers before as discrete components, but it was cheaper (and more convenient) to buy these modules. In case it's not clear, this is a fixed-frequency piezo buzzer at about 4kHz; in other words it's either on or off. Sound level is about 80dBA and the current draw is around 7mA Outer 2 pins only connected, it's a polarised device so ground pin is '-' and put a positive voltage on 'S' (3.3 or 5v, though the module will take up to 16v).
