For the low-priced and flexible Arduino board (www.arduino.cc) a BORIS driver can be downloaded free of charge. The driver supports the communication via USB as well as via Ethernet (UDP) if the corresponding add-on component (Arduino Ethernet Shield) is available. The driver runs in all WinFACT versions (WinFACT 6 or higher). The driver package contains the BORIS driver, the DELPHI 6-source codes and the necessary firmware for the Arduino board. So it is easy for users to make own adjustments of the driver (e. g. for future Arduino boards).
