What is this thing?

Maybe you can guess from the other side?

Simple – it’s a funny kind of DIP switch, to manually configure 4 input pins as needed:

When used with internal pull-ups, this causes each switch to pull an I/O pin down when latched in the top position (as indicated in parentheses).

Works on any pair of ports and in any orientation, of course – but then the pin assignments will be different.

  1. Hehe, that’s a neat little DIP switch, I like that.

    Glad the question was rhetorical, I was going to answer “Toast rack for a Barbie doll”

  2. where did you get these?

  3. Hm, yes. And what is this good for?

    And it’s a bit redundant, as the bottom position gives the same result as if the wire is ‘unhooked’. Or do I miss something?
