Software
At the moment there are three programs which allow a connection to the chess boards of the company Certabo and via the Millennium ChessLink, a connection to the ChessGenius Exclusive board or The King Performance. Two of them behave like a UCI engine and you use the boards on any chess GUI with UCI support.
Completely new is an independent program interface for UCI programs with native support of chessboards called BearChess!
