This is a expansion board designed for Raspberry pi A + B + designed Specific HIFI DiGi+, adopt Wolfson company high-end digital chip, using the 12S interface, support 16 to 24 audio data formats and the advanced shake reduction technology could control the Intribsic period jitter in 50ps RMS; Reductive degree is high, supporting hardware method of controlling volume, and the user can cooperate audio player system to set up their own network HIFI player after using the expansion board. It's convenient that this expansion board also provide two output interface fiber (S/PDIF) and coaxial (RCA) for external device, user can get rid of PC power, boot off slowly, the power supply noise and so on .

Features:

1. Using Wolfson's end WM8804G chip, using I2S interface; support 16-24 audio data formats; distortion and dynamic is very good, tall 192kHz sampling rate support, advanced shake reduction technology can be intrinsic jitter (Intrinsic period jitter) control within 50ps RMS, the high degree of reduction.

2. The use of optical fiber and coaxial outputs two output interfaces, user-friendly external amplifier

3. Support in hardware volume control (I2C interface)

The power supply uses Raspberry Pi powered, no external power supply; and the use of π-type filter power supply design can effectively reduce the interference of power supply

5. The use of direct digital output I2S interfaces, reproduction and high non-USB interfaces DAC mode, do not use other extensions GPIO Raspberry Pi
