What is Audio Module?

The Audio Module software helps users play back stored audio files from a micro-SD memory card. The module supports 4-bit ADPCM audio files (.ad4) with sample rates from 6kHz up to 32kHz. The compact 14-pin module takes up little board space and is recommended for any application that needs embedded audio. The .ad4 file can be saved to a uSD card and playback can be regulated via one of two methods: key mode or serial mode.

The key-mode gives a stand alone operation where a host micro is not needed. With only 3 push buttons, a 3V battery and a speaker, an intense compact and low component count MP3-Player like system can be applied. The serial-mode extends a plain, 2-wire interface to any micro-controller through its DATA and CLK lines. Audio operations such as PLAY, PAUSE, STOP and VOLUME control functions are all accessible to the host micro by using simple serial commands.
