MP23ABS1TR analog microphone (MEMS)

Bluetooth audio receiver module that allows wireless transmission of sounds. It is equipped with a PCB antenna and a 3.5 mm Jack audio connector

Mini MP3 player with microSD card support. It can work as a separate device and play sounds from the card or be controlled via the UART serial interface. DFRobot DFR0299

LC filter connected to the output of the DC power supply with a voltage from 0 to 50 V and a maximum current of 2 A. It reduces voltage ripple and interference caused by the power supply

An interactive addition to the BBC micro:bit that lets you create music using 15 touchpads that function like piano keys. The module has a built-in amplifier and speaker, so it doesn\'t require additional audio equipment. Powered via micro USB, it automatically supplies power to the micro:bit, simplifying operation. The keys can perform musical or control functions, making the :KLEF Piano ideal for educational, creative, and hobby projects. Kitronik 5631
