My advice: Do not plug that thing back in until you’ve figured out what the pinout of it is, and how it *should* be connected to the Diavolino.
>could you offer a better description of Note 1?
The “black” pin on the Diavolino is electrically connected to the pin next to it.
>would it be easier to just bite the bullet and buy the adafruit USB->TTL ?
Of course, but not necessarily quicker. ;)
