Indeed, the board is not required. I've added a note to the Tindie description to that effect.

I created the board for an upcoming Clojure/north 2020 talk https://clojurenorth.com/mike-fikes.html

But, your assessment is correct... the software is definitely the interesting bit (the challenges associated with getting ClojureScript to run on that hardware, with a REPL, etc.)
