Quick checks for different boards

[Dar-Scott]

So far, all candidate boards can print out a USB virtual serial port. Beyond that, things might differ. Serial output is the one thing in common.

At this point GAEN Sniffer.py is the only board app that does not depend on board features except BLE. (It is the only board app at this point.) Data is Python printed out the USB serial port.

This might be used as a quick check for boards mentioned on the Notion page.

Should a clone be used to do the checks?
Should a pull request be made to do the checks and to make any changes to make boards work?
One then the other?
