With serial communication, you can use all predefined commands or even the combinations of them to play the music. This module also supports general file systems like FAT16 and FAT32. It gets a Grove UART interface, a 3.5mm audio jack and a micro-SD slot. With this module, you can get some “voices” for silent applications.
