So my last project where I was going to convert a TASCAM CD Player into a Volumio Streamer was a bust, so now I have had to look at alternate plans for this one, I seem to be on the right track, BUT, there is something I am confused about and I need someone’s help, so here goes:
So I have 3 items that I need to add to my build:
- Hifiberry Digi2 PRO
- Power Management Board
- Rotary Encoder
All using the GPIO Pins.
Now I heard of the GPIO Expander, but it needs to have a certain chip (MCP23017), is there anywhere I can find a board that is already made and assembled?
Hope this makes sense.
