Player Mini is a compact and low-cost MP3 module that can be directly connected to speakers. The module can be used independently by combining with a power supply battery, a speaker, and buttons, or it can be controlled via a serial port and used as a module for Arduino UNO or any single-chip microcontroller with a serial port. The module has a hard decoding function for MP3, WAV, and WMA. Additionally, the software supports TF card drivers and supports FAT16 and FAT32 file systems. By simply using simple serial port instructions, it can complete the functions of playing specified music and how to play music, without the need for complicated low-level operations. It is easy to use, stable and reliable.
