Honey House Debug Cable and Raspberry Pi USB Programming USB to TTL Serial Cable This is a easiest way ever to connect to your microcontroller/Raspberry Pi/WiFi router serial console port The power pin provides the 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 Install the Windows XP/Vista/7 (Windows 8 not supported) or MacOS X PL2303HX. drivers on your computer and connect with a terminal program at 115200 baud 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
