!!!before all: please be CAREFULL, you can destroy electric parts.!!!

You have two options for connect BT module to PC.

1) you can use some FTDI (usb <=> serial), with 3.3V logic. Like this http://www.dx.com/cs/p/ftdi-basic-progr ... UMNiBfdLnY


2) you can use cable from spirit (usb pc cable), but you have to add some axternal power (4V - 6V, !!!6.5V is DEADLY for BT module!!!), do you need better wiring?

RX to orange on spirit USB cable
TX to red on spirit USB cable
or can be inverted, it depend on marking USB module.

For communication with BT module you can use some PC SW like this http://www.compuphase.com/software_termite.htm#_ . Your BT module look like JY-MCU

And again, please be carefull you can destroy PC, USB cable and BT module. A better way is to buy original BT module.
