I2S is a communication protocol specifically designed to carry digital audio signal. The Odroid-C4/C2/C1+/C0 has a dedicated I2S pin that you can connect to a Digital-to-Analog Converter (DAC) board making it a capable audio platform. The HiFi Shield Plus is driven by a powerful Burr-Brown/TI PCM5102 DAC chip to give 16, 24 or 32 bit audio formats with minimal distortion (-93dB) and ideal dynamics (110dB+), plus amazing sampling rates of 384kHz. It plugs right on top of the Odroid board and confined within the same footprint. The board provides stereo RCA connectors and a 3.5mm stereo jack (all gold-plated) to connect to external amplifiers and other audio equipment. The dedicated S/PDIF interface is newly added in the Plus version which supports up to 192kHz/24bit resolution via new Optical (Toslink) output.
With this board, you can enjoy a HiFi quality audio playback for internet radio or your local audio files.
This shield is not supported in Android.

Volumio
RuneAudio
... and many more
Fully assembled - no soldering required. Standoffs are included
No external power required - the HiFi Shield Plus is powered by the Odroid board
High quality components
Audiophile grade resistors, capacitors and gold plated RCA terminals and 3.5mm audio jack
An ultra-low noise dropout regulator is coupled with two solid capacitors for the power supply, significantly reducing power supply noise and greatly increasing the signal to noise ratio
The PCB surface is comprised of gold-plating on top of 2 oz. of copper, ensuring signal continuity and reducing signal reflection and refraction
