Selected User Reviews For uxcell 9mmx5.5mm Electronic Alarm PCB Panel Mounting Piezo Passive Buzzer Sounder (Pack of 10)

The feedback buzzers are tiny and good

5/5

The audible feedback can be used for keyboard or remote control Driven by PWM signals, these are operated at a high rate of speed. With an esp32 microcontroller, I'm controlling a variety of devices. What I like about these is that the bottoms are sealed There is a clearly marked polarity indication on the antennas and enable them to be driven directly by Beadboard can be used with these, but creative angles are needed to make it work.

I expected it to be just like that

5/5

A passive piezo speaker system with ten units. There should not be too much noise, neither too little. The square wave comes in, the sound comes The exact opposite of what you expected.
