I've connected the gnd to 7.2v and the pin vin to the minus of the battery... as result the chip near the DC power connector blow up! Ok... now I have two questions 1-Which is the name of the chip? There's written something like 113nf 2-Is that chip the only thing I broke? I'm so afraid T_T

I reversed gnd and vin...

Make sure the part you purchase has the same pinout as what's on the board.
