Narrowing Down Hardware Choices

I am working on making good hardware choices for the first version of the ChatterBox. There are so many good choices, it’s difficult to narrow down. I’d like to support somewhat of a variety, so I can include a board from a few different major vendors. The test rig in the image is something I built to try out different hardware configurations without having to build completely separate devices. I can swap different pieces out quickly and ensure my code remains compatible across all the devices I want to support.

As you can see, the choices are currently centered around Arduino (MKR Zero and Nano IOT 33), Adafruit (M0 Feather), and as soon as I receive it, a Sparkfun board as well. I’m also checking out a few different touch screen options.
