Active Buzzer Module 12V

This is a small buzzer module which operates around the audible 2 kHz frequency range. It is an active buzzer, which means that it produces sound by itself, without needing an external frequency generator. It can easily be used with microcontroller boards, like Arduino, without needing a dedicated PWM channel.

Features:

• Operating voltage range: 12v
• A mounting hole for easy installation
• Small size: 3.3 x 1.3 x 1.2 cm
• External GND
• External pin for enable

Specifications:

• On-board ACTIVE buzzer
• On-board 8550 triode drive 
• Can control with single-chip microcontroller IO directly
