This is a commonly used passive buzzer module, it mainly uses 12*9.5MM 5V source buzzer component. The active buzzer component has its own oscillating circuit. When controlling, the GND VCC on the block is powered on, when the signal terminal S is high, the buzzer will automatically sound.
The anti-reverse insertion white terminal with a pitch of 2.54mm, At this time, we can stack a sensor expansion board on the microcontroller. Module and self-contained wire connection, and then connect to the sensor expansion board, simple and convenient.
