MP3 Micro SD Player
- Overview
- Drivers
- Samples
Play MP3 audio/music from files found on the attached Micro SD card. The audio quality is reasonable and single mono channel. There is no system load as the module only receives and processes simple commands, like start playing, or stop. The files on the Micro SD card are saved in standard FAT16/FAT32 file system and can handle SD cards up to 32GB. Note that you will not have access to the files directly. Only the MP3 decoder can read the files. You will need to move the Micro SD card to a PC to load it with MP3 files.
Micro SD card is required and is not included.
