Description


1. The WTV020SD is a small, simple IC for embedding audio-playback into your next project. These devices are commonly used in children's toys and "talking" retail displays. This breakout board allows you to access the functionality of the WTV020SD to give a voice to your next project


2. The breakout board includes a battery connector and a micro-SD card slot. Simply load your audio files onto a micro-SD card and plug it in, power up the module and trigger the playback. Playback can be triggered in either key or serial mode:


3. The key-mode provides a stand alone operation where a host micro is not required. With only 3 push buttons, a 3V battery and a speaker, an extremely compact and low component count MP3-Player like system can be implemented.


4. The serial-mode provides a simple, 2-wire interface to any micro-controller via its DATA and CLK lines. Audio operations such as PLAY, PAUSE, STOP and VOLUME control functions are all available to the host micro via simple serial commands.
