Orange PI Hi-Fi Hat

What is it?

This is Orange Pi Hi-Fi Hat, that adds Hi-Fi audio capability to your Pi. It uses native I2S output of Orange Pi together with Texas Instruments’ wonderful PCM5102A Hi-Fi DAC.

Why did I build it

I want to bring modern hobbyist technologies to the world of ‘large speakers and amps’ tech. I build systems that keep that old-schoolish look, but adds online streaming and smart remote capabilities. I build this project as a possible core of such solution, where small but much capable box with Orange Pi in it drives large Pro-sized and Pro-sounded audio solution.

Why HIFI Hat?

It is simple yet powerfull solution, that adds audio capabilities to your Orange Pi based project. Audio quality complies with Hi-Fi standards, which means it is suitable for high quality audio streaming, just like bigger Raspberry Pi players.
