isoUSBRS422 is an isolated USB <-> RS422/RS485 converter board (~5x5 cm). It should work with Windows, Linux and MacOSX (not fully tested for all operating systems by me).
You can find video tutorials and other details on the project web page:

BOM Contains bill of materials of board
Driver Contains necessary drivers. Online Windows 7 (and probably newest versions) should install driver automatically. If you are running on an offline machine you may use drivers at that folder. However, I strongly recommend to get the newest driver from USB chip vendor website: http://www.ftdichip.com/Drivers/VCP.htm I won't update drivers at that folder when FTDI publishes new drivers. They are latest drivers at that time.
Firmware Contains profile file for utility called FT_Prog (contains in Utility folder). Once you finish isoUSBRS422 board, FT230x will not work as RS422/RS485 converter. This chip should be programmed only once. You may use the given profiles for proper operation.
Gerber Contains Gerber files for PCB production. You may produce exactly same board as mine using these files.
KiCad Contains KiCad project files. My KiCad version is (2013-07-07 BZR 4022)-stable. You should able to open project files and edit according to your needs (please consider license).
PCB Contains ZofzPCB (see: http://www.alperyazar.com/r/jHtc3 ) rendered board file and some computer generated images of PCB.
Schematic Contains PDF of schematic.
Utility Some programs to program isoUSBRS422 board an test it.
