Adafruit METRO 328 DC jack

The description says "polarity protected" - does this mean any polarity of DC is OK, or that if you connect the DC backwards nothing bad will happen (i.e., series diode or whatever)?

Yes indeed, and it looks like center positive as well. Of course, I have umpteen center negative wall warts!

Thanks

Many boards have been sacrificed due to operator inattention, (RIP...)
