Just got mine in the mail today. There are no indications on the device as to which pin is which. Also, do the Rev B docs match Rev C?

Thanks

    It's referred to as a "bump" and it's poor form.

    I know that Rev B was a major redesign using a different (newer and simpler to use) FTDI chip. I don't know anything about Rev C. I would suspect that there's nothing obviously different from the customer's standpoint. There is a top surface and a bottom surface and I suspect the schematic refers to the connections seen from the top. I don't have a Rev C, but there must be a painted dot next to pin 1 of the output connector.

    I apologize if the bump was poor form. Just didnt want to burn up a brand new toy. Thanks mike for the insight.

    Shawn, Mike is correct...bumps are not good forum netiquette...however seeing as you've had no official answer I will send this link to the engineer who made the changes to see if he can offer anything useful to you. Take care.

    Shawn,
    The connections are silk screened on to the PCB. Look for the 'VSS', 'RX', 'TX', and 'RES' labels for ground, receive, transmit, and reset, respectively. They are also shown in the diagram labeled 'Top View' on the first page of the documentation.

    Electrically, Rev B and Rev C are identical, and the same documentation refers to both. The link on the web page was outdated, and I just had it updated to reflect both Revs B and C.

    Let me know if you have any other questions,

    David-
    I checked mine, there are no connections silk screened on the device. However, if it is electrically the same as the Rev B, then I'm good to go! Thank you.
