> This is an expansion board designed for Raspberry pi 2 model B & B+, adapt 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 Intrinsic 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 the PC power, boot off slowly, the power supply noise and so on.
?It provides power indicator light for you to observe the expansion board status easier. It also support in hardware volume control (I2C interface).
>It supply with Raspberry Pi power supply, no external power supply; and the use of ¦Ð-type filter power supply design, effectively reduce the interference of the power supply. PCB board with gold plating on the tall, curved traces (high-end HIFI DAC is using curved alignment).
> It is to better ensure the continuity of the impedance signal to reduce signal reflections and refractions. Good sound should thanks to the real materials, optical interface using HIFI-class high-quality fiber seat, coaxial interface is used Pluses audio isolation transformer at the same time provide good audio digital audio device you are well protected and board! ! !
> It is integrated infrared receiver function. When there is no network, it is easier to control playback. I2S interface are using direct digital output, reproduction and high non-USB interface DAC mode. Do not use other extensions Raspberry Pi GPIO.
Packing List:
● 1 x HIFI DiGi+ Module
