The board includes a USB-C connector to mount it as a removable USB drive on a connected computer, a µSD card slot for connecting a compatible SD card, and a 3.5mm TRRS connector for headphone audio output. Controlling the MY1690X-16S over serial does require a USB-to-UART conversion, so a development board like the [RedBoard Plus](https://www.sparkfun.com/sparkfun-redboard-plus.html) is required. The MY1690X-16S operates over a serial-UART interface at 3.3V TTL using a command set to control audio playback (Play, Pause, Next, etc.), volume and equalizer settings, and query statuses (SD card contents, track name/length, etc.). We've written an Arduino library that simplifies this to a simple interactive text menu for all available commands to control the Audio Player Breakout with an Arduino development board. When plugged in over USB, the MY1690X-16S automatically mounts as a removable USB drive to transfer and view audio files to a connected microSD card. However, our testing found the transfer speed to be fairly limited. Sparkfun recommend loading large audio files directly to the microSD card using a USB reader or plugging the card directly into an SD card port on a computer. The board's audio output is powerful enough to work well with headphones but requires an amplifier for output on larger speakers. ### Features & Specs - MY1690X Serial MP3 Decoder - 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 - Supply Voltage: - VIN: 3.4-5V - VUSB: 5V - 0.1in.-spaced through hole headers - MY1690X UART (TX/RX) - MY1690X Card Detect - MY1690X Busy Signa - Power (VIN) and Ground - 1x USB-C Connector - Mounts as removable USB drive - 3.5mm TRRS Audio Jack - MicroSD Card Slot ### Documentation - [Schematic](https://core-electronics.com.au/attachments/localcontent/SparkFun_Audio_Player_Breakout_MY1690X-16S_28613856c62.pdf) - [KiCad Files](https://core-electronics.com.au/attachments/localcontent/SparkFun_Audio_Player_Breakout_MY1690X-16S_27907c1a301.zip) - [Board Dimensions](https://core-electronics.com.au/attachments/localcontent/SparkFun_Audio_Player_Breakout_MY1690X-16S_982247bc8c7.jpg) - [Hookup Guide](https://docs.sparkfun.com/SparkFun_Audio_Player_Breakout_MY1690X-16S/introduction/) - [Datasheet](https://core-electronics.com.au/attachments/localcontent/MY1690X___16S_MP3_Decoder_IC_User_Manual_11224144b5a.pdf) - MY1690X - [SparkFun MY1690X MP3 Decoder Arduino Library](https://github.com/sparkfun/SparkFun_MY1690_MP3_Decoder_Arduino_Library) - [GitHub Hardware Repo](https://github.com/sparkfun/SparkFun_Audio_Player_Breakout_MY1690X-16S) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/B/O/BOB-28038-1.jpg)
