PIFI DAC expansion board (PiFi DAC +) is dedicated for Raspberry Pi 2B/3/B +, which features TI's higher-end DAC chip (PCM5122), I2S interface(non-USB interface). It supports volume controlled by hardware (the old DAC uses PCM5102A chip hardware, which can not support volume controlled by hardware). With this extension board, users can use it with audio playback system (eg: volumio, xbmc system, etc.) to build their own network HIFI player.
