The 12V Goli Buzzer is a round piezoelectric sound device that emits a loud, continuous tone when powered with 12V DC. Known for its durability, loudness, and small size, this buzzer is widely used in alarm systems, warning indicators, timers, and electronic circuits.
Easy to connect with Arduino, Raspberry Pi, ESP32, STM32, or any microcontroller that can switch a 12V load via a relay or transistor. Just connect the positive and negative leads and power it with 12V for instant sound output.
