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).

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...
