Description

The HW-508 Passive Buzzer Module is a compact audio output device designed for Arduino, Raspberry Pi, and other microcontroller projects. Unlike active buzzers, this passive buzzer requires a signal (PWM) to generate different tones, allowing you to play melodies, alarms, and sound effects. It is ideal for DIY electronics, alarm systems, timers, and educational projects. The module comes with onboard circuitry and easy-to-use pins for quick integration.

Features

  • Passive buzzer capable of generating multiple tones and melodies

  • PWM-controlled—supports tone() function on Arduino

  • Wide operating voltage suitable for most microcontrollers

  • Compact and easy to mount on breadboards or project enclosures

  • Clear, loud sound output

  • Simple 3-pin interface (VCC, GND, Signal)

  • Ideal for DIY alarms, timers, notifications, and sound projects

Specifications

  • Model: HW-508

  • Type: Passive Buzzer Module

  • Operating Voltage: 3.3V–5V (typical 5V)

  • Control Signal: PWM (square wave)

  • Interface Pins:

    • VCC – Power input

    • GND – Ground

    • I/O (S) – Signal/Tone input

  • Sound Output: Custom tones (300 Hz to 5 kHz depending on signal)

  • Board Size: ~19 × 15 mm (approx.)

  • Mounting: 2-pin or solder pads

  • Material: PCB + electronic components
