Works as a standard active buzzer or you can apply PWM to play tiny, bleepy tunes. Ahoy!
Connect a voltage (4-8v) to the pins to make Dumb Noise (tm) or use a PWM from a microcontroller to change the tones - check out this Tom's Hardware article for how to play tunes using a Raspberry Pi Pico!
It's got sturdy, labelled pins for connecting to jumper jerky or poking into a breadboard. The specs list the minimum voltage as 4V, but we found it worked fine with 3.3V from a microcontroller. Note that you need to connect it up with the right polarity for it to make noise, even if you're planning on going down the PWM route.
