SparkFun Serial MP3 Player Shield – MY1690X-16S (Qwiic)

With the SparkFun Serial MP3 Player Shield, turn any Arduino into a standalone audio player. Play MP3 and WAV files from a microSD card with simple serial control!

The SparkFun MY1690X Serial MP3 Player Shield is an awesome decoder that can store music files onto a standard microSD card, allowing you to add music or sound effects to any project. With this board, you can pull MP3 and WAV files from a microSD card and play them using only one shield, effectively turning any Arduino into a fully functional stand-alone audio player!

The MY1690X is controlled through a serial UART port. With a memory card (up to 32GB) formatted to FAT16 or FAT32, the MY1690X decodes MP3 and WAV files and outputs audio to a TRRS connector. You will just need a pair of headphones to jam out to your favourite tunes. A USB-C connector is populated to mount the microSD card to a computer easily. ESD protection diodes and 5V/1A resettable are included for protection. Once it shows up as a drive, audio files can be added or removed from the memory card. Up to 65536 tracks can be loaded and played back from the memory card.

Schottky diodes are also included for protection when powering the shield through the USB-C connector or an Arduino’s 5V pin. A horizontal Qwiic connector is included for users interested in easily adding Qwiic-enabled devices for Arduinos that do not have a Qwiic connector populated. Easy access to the reset pin is provided with the reset button populated. Status LEDs for power and playback are also included.

This shield does not have headers installed. Additionally, you will need an audio amplifier to connect the output to speakers.
