Hifi Shield Plus

The Hifi Shield Plus board boasts RCA connectors and a 3.5mm stereo jack which are all gold-plated easily connects to an external amplifier and other audio devices. This board will work well with the ODROID-C2 / C1+. This is not compatible with the original ODROID-C1 though.

Burr-Brown supports 16, 24, 32-bit audio formats (-93dB) and ideal dynamics (110dB+) with sampling rates of 384kHz.  The Hifi Shield Plus board has a dedicated interface that supports up to 192kHz/24 bit resolution via new Optical output.  The following audio playback can be used: Volumio, RuneAudio or XBMC/Kodi for HiFi audio via the I2S expansion on the C2 / C1+ boards.

Functional introduction:

1. The output ports include gold-plated stereo RCA terminals and a 3.5mm audio jack.
2. 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.
3. The I2S interface allows for direct decoding of the digital input to analog output using master clock synchronization.
4. The PCB surface is comprised of gold-plating on top of 2 oz. of copper, ensuring signal continuity and reducing signal reflection and refraction.
5. ODROID-C1+ supports up to 384Khz while the ODROID-C2 supports up to 192Khz.
6. This HiFi Shield Plus is partially functional on Android. The output format is fixed at 44.1Khz/16bit stereo due to limited AOSP audio HAL implementation.
