The mikromedia for XMEGA® features stereo audio codec 

VS1053

. This module 

enables audio reproduction by using stereo headphones connected to the system 
via a 

3.5mm

 connector CN2. All functions of this module are controlled by the 

microcontroller over Serial Peripheral Interface (

SPI

).
