Here is the sample project for Unity, which includes the code that will be used for connecting games to the board.

Please let me know if you need any further information. Additionally, we are having some minor issues with the configuration of the board so that file will need to be updated soon! For now there is a version of that configuration file in the project, it is just not the final one. With all the jostling of traveling cross country, we have to do some minor hardware fixes before we can update the software, and that process will not be completed until early next week.
