sounds like you fried something, unless you got a smt soldering iron, your better off buying a new module. if you do have a smt tip, you can try and desolder the lt1615 and replace it. fyi, i always use a diode in series with the positive side of my power supply to avoid reverse polarity or shorting out the regulator, etc

page 13 of the data sheet says to set reg 0x03 (clock div) to 0x90 to get 90 frames/sec, but the seps525 data sheet says to make it 0x30 for 90 hz. can you update your data sheet? thanx, good product btw!!
