Usage:
For use, the board is mounted directly onto the Arduino UNO and controlled using the SFEMP3Shield library. The TF or microSD card must be formatted in FAT32, then audio files are copied to the card and renamed in order, for example track001.mp3, track002.mp3, track003.mp3.
After inserting the card into the slot, the module can play audio files directly from memory, making it suitable for DIY projects, audio players, voice announcement systems, or other multimedia applications.
For proper operation, it is recommended to use compatible file formats and power the board at 5V DC through the Arduino UNO. The shield communicates via the SPI interface, and the integrated microphone also allows real-time audio recordings, depending on the project configuration.
