    Yes... I think the most popular will probably be the pinned one, which is what I'd do initially I think.


    I've had a look at this and yes, I think it can be done without increasing the board size. Not it just comes down to whether the PCB manufacturers will do it without charging a load extra.

    As you say, shorts might be more of an issue, but it's probably not good practice to leave the board floating around uninsulated anyway...
