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

Features

• Operating voltage range: 3.3 to 5 V
• A mounting hole for easy installation
• Small size: 3.3 x 1.3 x 1.2 cm
