• Cool, thanks Gordon.

    I was just looking through the pins earlier trying to get an idea of to map them, but not come up with anything yet. Good point about the pins not being v5 tolerant aswell, that wasn't something I'd thought about. Should it be possible to use a single divider for all inputs? or would each pin need one? (Sorry, I'm not much of an expert on this, I'm still learning as I go).

    Rgarding NRFC etc, wouldn't it be more of a case that they use existing shields and just stack them? rather than soldering them to the board direct?
