I got one and I'm starting to experiment. I discovered that soldering can be a problem. First, I had to buy a solder. Second, physics is merciless and a mistake can toast your card (didn't happened to me yet) vs the run-fail-debug loop we're used to in sw development.

Anyway, some hw modules have been tested with Espruino and the web site explains how to use them. My understanding is that you can plug almost anything into it, you just (!) have to know its specs and how to wire it to the board.

Yep, lots of good tutorials, and the creator of the board is quite helpful on email.
