Buzzer Module
This module is a compact, easy-to-use passive buzzer component designed for embedded systems and prototyping. It features a standardized 3-pin interface: VCC (5V), Signal, and GND, allowing seamless integration with a variety of microcontrollers, such as Arduino
, ESP32
, CH552
, and STM32
boards.
NOTE: The buzzer onboard can generate audible signals for use in alarms, notifications, timers, and user feedback systems. Its design includes a pre-mounted drive circuit, enabling direct digital control from microcontroller GPIO pins.
