OK -- well, with that board, you are simply exposing the serial port directly to the PC (like a serial to USB adapter, but working off TTL serial levels instead of RS-232 to make a long story short). 

You would then have to either use Undersampled software OR fiddle with the wacom drivers to make it work (I do not recall if anybody got that to work, maybe yes -- you would have to search the forum -- this is only for Windows btw).  With Linux, there is a very good chance the drivers will work fine with the FTDI board. I never did that myself. If you use Undersampled software, it will only control the "mouse" (works only in Windows) -- so you miss all the "pen special features".  Like the "pressure" and the "eraser".

If you opted for the Teensy board, then this is totally different. Your tablet would be "converted" to a Wacom USB tablet (using the WaxBee project) and you could use any of the recent Wacom drivers for any OSes and popular operating systems.

None of the solution is perfect. I am working towards making the waxbee project better and fixing issues as they occur. Wacom does not support serial-based tablets anymore (althought it does support tabletPCs that have serial-based "internal" penenabled sensors).

Undersampled posted the pinout already. And trust me, a photo would not make it more easy to understand. (a diagram yes, but then someone would have to pass some time to draw it. Besides, I am sure you can read a "table"). You would have to search for that -- look at his "latest posts" and search that. It should not be that difficult to spot. (Start looking at his most recent posts first).

http://wiki.bongofish.co.uk/doku.php?id=bongofish:penenabled  is the place to start -- links to various threads -- you have the model of the digitizer?  You have to remove the LCD Panel to see it in the back.
