I have a 6 pin Serial to USB cable from FTDI (TTL-232R-3V3). Here is the spec: http://www.ftdichip.com/Support/Documents/DataSheets/Cables/DS_TTL-232R_CABLES.pdf
It works on the galileo gen 2 board.
I know that the FTDI cable for raspberry pi has only 3 cables (http://www.ftdichip.com/Support/Documents/DataSheets/Cables/DS_TTL-232R_RPi.pdf), for Rx, Tx and Gnd.
Can I use the TTL-232R-3V3 6 pin cable to connect to the RPi via serial interface? I'm not sure, but why shouldn't it work if I just connect Rx, Tx and Gnd?
thanks
