BPT-14

Module with a buzzer (without generator) controlled by a digital interface. It allows you to generate simple sounds by changing the frequency of the control signal. DFRobot DFR0032

Module with a buzzer designed for Wemos D1 Mini tiles. It allows you to generate simple sounds by changing the frequency of the control signal

Sound module supported by I2C interface, which allows to generate sound signals in simple projects thanks to Qwiic system and ATtiny84 microcontroller. With support of Arduino libraries, users can control volume, frequency and duration of sound, which makes it ideal for applications such as alarms or signals in robots. SparkFun BOB-24474
