Python library for integration in chess software

Dominik Schlosser

Suitable for:

  • Linux, USB, Bluetooth-LE
  • Raspberry PI, USB, Bluetooth LE
  • Windows: USB
  • MacOS: USB

The software is designed in such a way that it is easy to add new transports (e.g. other Bluetooth variants).

On the basis of our interface definitions for the chess link, Dominik Schlösser has written a library for the Python programming language, which allows a comparatively easy integration of the interface into existing chess software products. The project is currently still in its early stages, and is designed to allow chess software developers to quickly integrate the ChessLink and the Millennium exclusive checkerboard.

The library supports:

  • Automatic hardware detection on USB
  • Automatic Bluetooth search
  • Train display via LEDs (optional display of 4 deductions in the analysis mode via LED sequences)
  • Interoperability with Python-chess
  • Fen Import
  • Position setup via board or Fen
  • UCI engines (tested with Stockfish and Leela chess Zero)

The library abstracts the details of the log, and provides functions such as: querying the position of the Millennium Board in fen format, passing the user’s train to the engine, Signalisi the engine’s train by LEDs

Our request: If you want to use the library or our interface, please inform us briefly about your project and also about the completion. We would like to pay tribute to successful implementations and make them available to all users at this point. Simply send a short email at

The necessary files-including the complete interface documentation from the ChessLink-can be found on Github.

Dear creators!

This being an open system, the specifications are released to any interested developers worldwide. The MILLENNIUM interface code can be integrated into any GUI, e.g. Android or Apple iOS smartphones and tablets, as well as Windows or Apple Computers.
