DIY: Arduino PGA Audio Preamp, PSU
with this revision, we now have a matching psu board. cabling is simplified and solderless (IDC jacks and headers). analog voltage is fed into the board via one cable and 2 digital 5v via another (cpu and relays).
I had a rear panel leftover from another project and used those panel-mount rca jacks instead of the board-mount ones that fit properly to the preamp board.
the power button is not yet wired up (so far, I've not missed not having it work) ;)
interior-wise, its a pretty clean install. once I have new rear panels that match this board's jack layout, it will look even better.
