Product description: Module with active buzzer - Qwiic - SparkFun BOB-24474

A convenient solution for anyone who needs to add a sound function to their electronics projects. The module from SparkFun , based on the ATtiny84 chip, uses the Qwiic system, which allows easy connection to microcontrollers and other devices via a cable , eliminating the need for soldering and simplifying the integration process. The module uses built-in transistors to control the volume. There are two LEDs on the board - PWR , which lights up when the power supply is connected, and STAT , which lights up when the buzzer is active. With compact dimensions of 25.4 x 25.4 mm , this buzzer is perfect for small projects where space is limited. It is an excellent tool for prototyping and quick testing of ideas.
