The cable is easiest way ever to connect to your microcontroller/Raspberry Pi/WiFi router serial console port. Inside the big USB plug is a USB<->Serial conversion chip and at the end of the 1 meter cable are four wire - red(power), black (ground), white (RX) into USB port, and green (TX) out of the USB port. The power pin provides the 5V @ 500mA direct from the USB port and the RX/TX pins are 3.3V level for interfacing with the most common 3.3V logic level chipsets.

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.

If you are running Windows 7/8/10 etc, check this tutorial page with links to drivers for both PL2303 and CP2102
If you are running Mac OS X, check this tutorial page with links to drivers for both PL2303 and CP2012
If you are running Linux, drivers are already included in the kernel, no need to install anything!

Also handy for hacking WiFi routers to install alternate OS's, or nearly any other 3.3V logic serial port. This is easier to use than an FTDI cable in many cases because the wires are separated. Note that we call this a "TTL cable" (since that's what they're called) but technically it's CMOS logic.

This cable is not good for Arduino re-programming such as a BBFuino, Pro-Mini, etc. because it does not have the DTR/RTS wire necessary for initiating the bootloader reboot sequence.
