SP5T MP3 Player Module — Clear, easytointegrate audio playback Key benefits Simple playback from removable storage: plays audio files stored on a TF card or U disk (maximum 32 GB, must be FAT32). This makes storing and updating audio straightforward. Easy integration and control: the module is controlled via UART, allowing direct control from microcontrollers, PLCs, or other serialcapable systems. Readytouse audio decoding and output: decodes MP3 and WAV files and provides 1 W output power for direct driving of small speakers or audio stages. Fast file updates: change or voice files using USB downloading and the included PC application software for convenient management. Features and specifications Supported formats: MP3 and WAV decoding. Storage: TF card or U disk up to 32 GB (FAT32 required). Control interface: UART serial control for play, stop, track selection and related functions. Output power: 1 W. Software: PC application software included to simplify configuration, file management, and updates. File updates: voice/audio files can be changed via USB download. Form factor: modulelevel design for straightforward integration into larger systems. Why customers choose SP5T Reduces development time: builtin decoding and UART control eliminate the need to design custom audio decoding hardware or complex firmware. Flexible content management: use standard FAT32formatted TF cards or USB flash drives to manage audio files across devices or installers. Reliable operation: supports common audio formats (MP3, WAV) and provides a defined 1 W output for predictable performance. Typical applications Interactive kiosks and pointof displays: play prompts, product descriptions, or background announcements controlled from a host system. Toys and learning devices: store multiple voice files on TF card or U disk and trigger playback via UART commands. Equipment voice prompts and alarm systems: update voice alerts quickly over USB and trigger messages from a control board using serial commands. Integration notes Ensure storage media is formatted as FAT32 and does not exceed 32 GB. Control using UART commands from your microcontroller or serial host; use the provided PC software for file management and firmware/configuration tasks. Suitable for lowpower speaker applications where 1 W output meets audio level requirements. If you require additional technical details for integration (pinout, UART protocol, or wiring), refer to the SP5T module documentation provided with the product.
