Hello,
I plugged in my RockBlock 9603 and smoke came from U3. I'm guessing that's a 5v regulator? Whats the warranty? Can I get a new carrier board as I think the 9603 module is fine? Does anyone know the U3 part number I could probably just replace that chip thanks.

The power supply used sounds like your own not the included FTDI USB cable. Is that correct? In case you had not seen it this is the pinout diagram from the guide. It does mention a 450mA limit on the power supply.
