First off let me say that I am a teacher, and when I get a Raspberry Pi, I immediately pass it off to a student.
Long story short, said student misplaced my 5V usb power supply and somehow used a 12V supply. The polyfuse gives strange, as in not 5V, when supplied by a correct, 5V power supply.
Should I just chuck this Pi? Or is there a possibility the fuse saved the day, an I can just replace the polyfuse?
Thanks for your help with this.
