USB to TTL Serial Cable - Debug / Console Cable
This cable makes it easier than ever to connect to microcontroller/Raspberry Pi/WiFi router serial console port. Inside the USB plug, there is a USB Serial conversion chip and four wires at the other end, which are: red for power connection, black for the ground connection, white for RX into USB port, and green for TX out of the USB port. The power pin provides 500mA directly from 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 to the debug/login console on the Raspberry Pi. Connect the pins as shown to power the Pi and establish the RX/TX link, then install the Windows 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.
Also handy for hacking WiFi routers to install alternate OS s, or nearly any other TTL port, this cable 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 boot loader reboot sequence. For that we suggest to you use an FTDI cable.
