12vdc to digital pins

I crossed my wires setting up a card reader, the photon still comes up and connects to the cloud, though. So did I fry all of the pins or just the two that got the 12 volts?

You might be lucky and have only blown those two pins. I mean, if it works, it works, right? Does it get abnormally hot when in use?

Doesn’t seem to, but I immediately swapped for another one when I realized my mistake, I’ll plug it in now that I’m home and check.
