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 favorite 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. Sparkfun recommend the [Arduino R3 Stackable Header Kit](https://core-electronics.com.au/arduino-stackable-header-kit-r3.html). Additionally, you will need an audio amplifier to connect the output to speakers. ### Features & Specs - MY1690X Serial MP3 IC - Compatible with .MP3 and .WAV audio files - Audio Sampling Rate: 8-48K - Bit Rate: 8-320Kbps - FAT16 or FAT32 SD formats - MicroSD cards up to 32GB - Serial UART Command Set - Voltage Input: 5V - USB-C Connector - 6V/1A Resettable Fuse - ESD Protection Diodes for USB Data Pins - Reset Button - 1x 3.5mm TRRS Connector - MicroSD Card Socket - 1x Horizontal Qwiic Connector - Standard Arduino Uno R3 Footprint - 2x3 ICSP Passthrough - LEDs - Power - Busy/Playing - Board Dimensions: 53.34mm x 59.69mm (2.10in. x 2.35in.) ### Documentation - [Schematic](https://core-electronics.com.au/attachments/localcontent/SparkFun_Serial_MP3_Player_Shield_MY1690X_28385f989cb.pdf) - [KiCad Files](https://core-electronics.com.au/attachments/localcontent/SparkFun_Serial_MP3_Player_Shield_MY1690X_248161add04.zip) - [Board Dimensions](https://core-electronics.com.au/attachments/localcontent/SparkFun_Serial_MP3_Player_Shield_MY1690X_146765b248a.jpg) - [Hookup Guide](https://docs.sparkfun.com/SparkFun_Serial_MP3_Player_Shield-MY1690X/) - [Datasheet](https://core-electronics.com.au/attachments/localcontent/MY1690X___16S_MP3_Decoder_IC_User_Manual_11224144b5a.pdf) - MY1690X - [3D Model](https://docs.sparkfun.com/SparkFun_Serial_MP3_Player_Shield-MY1690X/assets/3d_model/SparkFun_Serial_MP3_Player_Shield_MY1690X.step) - [Qwiic Info Page](https://www.sparkfun.com/qwiic) - [Arduino Library](https://github.com/sparkfun/SparkFun_MY1690_MP3_Decoder_Arduino_Library/) - [GitHub Hardware Repo](https://github.com/sparkfun/SparkFun_Serial_MP3_Player_Shield-MY1690X) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/D/E/DEV-28021-1.jpg)
