I have my OSPI in my garage sucessfully running my 15 sprinkler stations. Since its in the garage, I thought I might as well use it as an mp3 player/media client. I have installed MPD, and also an UPnP renderer to listen to music both locally, and via my home network. Right now, I am using the mini stereo output hooked up to an old auto amp (12VDC, 25W), and then sent to some old truck box speakers. Obviously, the sound is not great, but good enough for now. I got to doing some research on DAC’s, and I’d like to get an I2S DAC.
My setup now is OSPI on a Raspberry Pi 2, so, to hook up the DAC I would need access to the GPIO pins. I’ve included a pic with the pins I need, I think???
The first question, is this even possible? If so, how?
