So there is a chance you just fried the VR. I would test it, it's an easy

As for getting away from the arduino formfactor... Sure for smaller
projects, it's nicer to just use the chips, and it's nice to lower the price
a bit. But there is something to be said about the community around arduino,
it's an accepted standard, and if you build boards using the shield model,
to take an arduino and socket it on, then if/when you release that design
it's MUCH easier for the average user to integrate, rather than having to
build the entire board (micro and all) from scratch.

Makes your projects more "approachable"

Just my 2 cents though ;)
