This is a special HIFI DAC expansion board designed for the Raspberry pi B+ ,using TI's DAC chip (PCM5122), using an I2S interface;
• The user can use this expansion board with audio playback systems (eg: volumio, xbmc system etc.) to build its own network HIFI player;
• The expansion board provides two kinds of output interfaces to facilitate external amplifiers and other equipment.
• It provides LED indicates working status. Red LED for the DAC power indicator (Power normal light), the green LED for the DAC working condition (when working decode light, stop, or does not work when off), a better understanding of the work of the DAC provide infrared receiver interface (occupied GPIO26)
