What is it?
The Orange Pi Home Media Center is a series of compact and neatly designed hardware projects that combine the power of the Orange Pi One board and the Hi-Fi DAC.
The HiFi version of the board uses the capabilities of the TI’s PCM5100 32-bit DAC with line-level output, while the Loud version is based on MAX98357A DAC with a D-class amplifier delivering 3-5W per channel.
This versatile media center provides a customizable and fully open-source solution for home entertainment.
With a minimalistic but functional design inspired by commercial audio gear, it offers a seamless user experience. It aimed to support Volumio, Mopidy, or any custom firmware you may come up with.
Why did I build it
Initially, I created a line-level Hi-Fi version of the board, followed by an Amped version. I use them myself with the off-the-shelf commercial amp to sort of modernize pre-internet-era audio gear with Spotify and the rest of the family.
It works great, but it lacks proper integration between the music source and the amp. I even connected the amp via relay, but you cannot control the input switch remotely, etc.
At some point, I came to the idea of a standalone device that would either connect to a commercial amplifier or have an amp on board. To complete the picture I added an IR input, so I can add remote control to the setup as well as RGB LED for visual feedback
Why Orange Pi?
It’s capable reasonably priced, and great value for money. But most notably, Raspberry’s availability is still poor at the moment of writing. Orange Pi is not a perfect alternative, and not nearly as good a support level as Big Pi. But in terms of audio quality, it is no compromise, and that is what matters most.
