3.3V-5V active & passive buzzer module, high/low level trigger optional, 3-pin interface, for MCU sound alarm, electronic DIY and experiment projects.
Description
Active / Passive Buzzer Sound Module
📌 Product Overview This active and passive buzzer module uses transistor drive circuit, available in 4 versions: active high-level trigger, active low-level trigger, passive buzzer. The working voltage supports 3.3V-5V, compatible with 3.3V and 5V microcontrollers. The passive buzzer has no built-in oscillator, needs 2K~5K square wave signal to sound, sound frequency is adjustable to play simple melodies. Active buzzer will make continuous sound once triggered by corresponding level signal. It adopts 3-pin wiring (VCC, GND, I/O), reserved mounting hole for easy installation. Widely used for sound alarm prompt, DIY electronic projects, MCU experiment teaching, equipment reminder system. ✨ Core Features- Driven by S8050 / S8550 transistor
- Operating voltage: 3.3V – 5V, compatible with 3.3V & 5V MCU
- 3-pin interface: VCC, GND, I/O
- With mounting hole for fixed installation
- PCB size: 32.2X13mm
- Active buzzer: high level trigger / low level trigger optional
- Passive buzzer: requires 2K~5K square wave drive, adjustable sound frequency, supports melody playback
| Parameter | Spec |
|---|---|
| Module Type | Active / Passive Buzzer Module |
| Drive Chip | S8050 / S8550 Transistor |
| Supply Voltage | 3.3V ~ 5V |
| Interface | 3 Pin (VCC, GND, I/O) |
| PCB Dimension | 32.2X13mm |
| Active Version | High Level Trigger / Low Level Trigger |
| Passive Version | Need 2K~5K square wave input |
- Active buzzer outputs fixed tone after receiving trigger level.
- Passive buzzer cannot work with DC voltage, square wave signal is required.
- Do not supply voltage over 5V to avoid burning the module.
- I/O pin should connect to MCU digital IO port.
