Sounds like a plan, man!
Thanks for the excellent feedback waltr & codlink!
Because eagle lite seems to have a better selection on components to start from, ergo the SCH is in eagle lite. I have a schematic, which is attached. I’ve yet to read the layout guidelines, but I will in the next couple of days. Some of the wires don’t seem to connect right in eagle when I move to layout components, but this is clearly a problem of me needing to read the manual.
Here are the links to the manuals for a few components of the board, as much for my reference as anyone reading this later.
