    Are the IO pins on the S2 Mini reprogrammed?
    Ground, Vbus, and 3V3 pins are in the same place, though the IO pin numbering is different, so any swaps would certainly require a bit of reprogramming for proper functionality. The S2 mini features two rows of header connections to the inside of the D1 mini-compatible pins in order to accommodate its expanded 27 broken out IO.
