PL2303 PL2303HX USB to UART TTL Cable Features

There are four wires: 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.

• Windows XP/Vista/7/8/10 or MacOS X 10.9 to 10.11 PL2303 drivers
• PL2303HX.D datasheet 
• PL2303TA datasheet

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.
