This easy to use module accepts USB memory stick or SD memory card for playback of MP3 files. The module is
equipped with CD player style functions ie: track skip/search, repeat, play/pause etc. The unit also has the ability to

files and begin playback.

the prev or next buttons are pressed. To pause playback at any time, press the play/pause button (>II).
