Probably a stupid question but I want to use this Arduino bluetooth shield with a 3.3v Arduino (the M0 Pro). The shield has a switch marked VDD, with the two options being 3.3v and 5.0v.

Is that what this switch would be for, for specifying the input voltage?

I looked through all of the documentation on Linksprite and can't find a concrete answer.
