AudioCARD
AudioCARD is a compact low powered audio player build around the very popular VS10011 – MP3 audio codec from VLSI.
AudioCARD can operate as a standalone audio player, automatically booting and playing content from its on-board EEPROM or SD/MMC card as soon as power is applied. In addition, it can be configured as a slave device, decoding an audio bit stream from an attached microcontroller.
Its compact size and low power consumption make AudioCARD ideal for integration into interactive displays and audio guides.
