Unlike active buzzers, it allows full control over pitch and duration via PWM, making it ideal for melodies, alerts, and user feedback in embedded projects. This compact module includes a built-in transistor driver for safe direct connection to microcontrollers.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e3V – 5V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eResonant Frequency\u003c\/td\u003e\n\u003ctd\u003e2.3kHz ± 0.5kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSound Output\u003c\/td\u003e\n\u003ctd\u003e≥85dB at 10cm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCurrent Consumption\u003c\/td\u003e\n\u003ctd\u003e≤30mA\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePin Interface\u003c\/td\u003e\n\u003ctd\u003eSignal (S), VCC (+), GND (-)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e12mm x 9.5mm (PCB)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eCustom alarm or notification sound for IoT devices\u003c\/li\u003e\n  \u003cli\u003eMusical tone player using Arduino tone() library\u003c\/li\u003e\n  \u003cli\u003eInteractive feedback for button presses or sensor thresholds\u003c\/li\u003e\n  \u003cli\u003eSimple doorbell or timer alert system\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis passive buzzer works with any 3.3V or 5V microcontroller, including Arduino Uno, Nano, Mega, ESP8266, ESP32, and Raspberry Pi (with transistor driver already integrated). Connect directly to a PWM-capable digital pin for tone generation. No extra components needed.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eConnect VCC to 3.3V or 5V, GND to ground, and Signal to a PWM-capable GPIO pin. The on-board transistor ensures safe current draw; no external resistor required. Use the Arduino tone() function or equivalent to generate frequencies.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.

Use pin 8 or any PWM-capable pin with the tone() function. No extra components required.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eCan I produce multiple tones or melodies?\u003c\/summary\u003e\u003cp\u003eAbsolutely. The passive buzzer relies on an external PWM signal, so you can generate any frequency within its range. Use timing libraries or the tone() function to play melodies or sound effects.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eWhat is the difference between active and passive buzzer?\u003c\/summary\u003e\u003cp\u003eAn active buzzer has a built-in oscillator and will sound as soon as DC voltage is applied, producing a single tone. A passive buzzer requires an AC signal (PWM) to create sound, giving you control over pitch and patterns.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
