Fantastic item, but don't reverse the voltage! – JY-MCU Arduino Bluetooth Wireless Serial Port Module Reviews

I got this up and running on a quadcopter for configuration and it was dead simple. The password is 1234 and the baud rate is 38400 by default. However I went to switch the RX/TX wires on the microcontroller, but accidentally switched 5v and gnd resulting in a puff of smoke. It comes with a nice connector wire, but it isn't color coded.
If you reverse the voltage it dies. It would have taken a $.01 diode to prevent this or maybe if it came with colored wires.
Great value, just double check your wires.
