Re: IR Board Fried?
Just get a new 5V regulator.
I can't tell you where to get it. I just used an old one from another old board.
Try and get a L805 if you can, if you can't... improvise.
I have already repaired our board twice. Both times it was because the 5V regulator died. It's too bad FIRST did not design the board with a diode to protect it from accidental reversed polarity.
