IP Audio Module 300

low cost version with limited feature set, one serial port, digital I/O, Decoding only, 3.3V supply.

The IPAM 300 is a universal, standalone, IP Audio function block which can be easily embedded into OEM products. The module decodes IP Audio streams and provides the decoded audio as a (stereo) analog or digital (I2S) feed. Supporting a vast range of protocols and codecs the module can be used for both VoIP and IP paging as well as high quality music distribution and IP music streaming applications. Control I/O (serial port, digital inputs and outputs) allow the use with UI and control interfaces. Most of the Barix Exstreamer products are based on this module.
