Because of the separated pin plugs, this cable is ideal for powering and connecting up to the debug/login console on the Raspberry Pi or BeagleBone Black. Connect the pins as shown to power the Pi or BBB and establish the RX/TX link. Then install theWindows XP/Vista/7 or MacOS X PL2303HX.A drivers on your computer and connect with a terminal program at 115200 baud. Windows 8 is not supported. If you're using Windows 7 and you have issues, try this Prolific driver version 1.013
Also handy for hacking WiFi routers to install alternate OS's, or nearly any other TTL port. This is easier to use than an FTDI cable in many cases because the wires are separated
This cable is not good for Arduino re-programming such as a Boarduino, MENTA, Monochron, etc. because it does not have the DTR/RTS wire necessary for initiating the bootloader reboot sequence. For that we suggest an FTDI cable or FTDI friend.
