Will the Departure Boards work in non UK countries?

Yes, as long as you have access to WiFi the board will work. The clock can be set to your local time zone from the dashboard, and it shows UK and Irish services. The board comes with a uk style wall plug power supply which can be run on 110v to 240v. You can swap this with any local 5v 3amp dc jack wall plug with the correct plug for your country.
