s/pdif switch display board

Making progress on my spdif switch (input selector and samplerate frequency display).

 

Here is the arduino nano sending test strings out to the 2 led display modules. pressing the switch on the left will cycle between the 2 inputs that I have planned (coax and optical).

 

wait, did I just spell 'opto' with zeros? lol. I'll have to change that to the letter Oh, I guess ;)

 

I plan to mount this to the front of a new chassis and have this module be the switch 'fabric':
