Unused GPIO and Audio inputs on the Daisy

Im pretty sure this has been covered before but i cant find the reference.

I’m performing some ground loop/noise problem solving on my PCB integration of Daisy and am implementing some additional filtering and ground loop isolators in my next version.

Before I send this new version off what should I be doing with the following:

  • Unused GPIO pins?

  • Unused R Audio In (Pin17) and Unused R Audio Out (Pin19). Its a Mono implementation.
