Chess set Millennium eONE Desktop International – king 5.5 cm, board 24×24 cm

The Millennium eONE Desktop International is a compact electronic chess set with international-style pieces and a king height of 5.5 cm and a playing board of 24 × 24 cm. Designed for tabletop play, the set pairs standard piece proportions with a small-format board for home, club or portable use. The eONE is an electronic sensor board that transmits moves in real time via Bluetooth or USB to compatible apps and platforms such as lichess.org, chess.com and Tornelo, while preserving the natural feel of moving physical pieces.

Advantages

The eONE combines fully automatic move recognition with an integrated 81-LED move display so you can play without pressing pieces or looking away from the board. Real pieces on sensor squares deliver a natural playing feel while the automatic transmission of moves to apps and chess programs keeps online games synchronized. Built-in Bluetooth and USB connectivity and a rechargeable lithium battery that supports at least 24 hours of play make the set easy to set up and use without persistent cabling.

Suitable for

• Casual players who prefer physical pieces while playing online
• Club members and coaches for training and remote play
• Players who need a portable electronic board for tournaments or events
• Users of chess platforms such as lichess.org, chess.com and Tornelo

When it may not be suitable

The compact 24 × 24 cm board and 5.5 cm king height are optimized for space-saving desktop use; players who prefer larger tournament-sized boards or taller pieces may find the format too small. Advanced users expecting a dedicated standalone chess engine with a full set of onboard AI features should note that the eONE is intended primarily as an interface board for online play and compatible chess software rather than as a self-contained engine console.

Key specifications

• King height: 5.5 cm
• Board dimensions: 24 × 24 cm (width × depth)
• Piece style: International standard proportions
• Move recognition: Fully automatic sensor detection (81 sensors)
• Move indicators: Integrated 81-LED display

How to use

Place the Millennium eONE on a stable surface and power it on. Pair the board via Bluetooth or connect by USB to your computer, tablet or compatible device and open the supported platform or chess program. Start a game in the app or on the platform; moves made with the physical pieces on the sensor squares are detected automatically and transmitted in real time. Use the LED indicators to follow move confirmations and suggested squares; charge the board when battery level is low to maintain continuous play.

What to consider before purchase

• Board and piece size: 24 × 24 cm board with 5.5 cm king is compact—ensure this meets your comfort and display needs
• Intended use: Designed as an interface for online play; not a substitute for a full standalone chess computer with built-in engine features
• Compatibility: Confirm compatibility with your preferred platform or chess software (e.g., lichess.org, chess.com, Tornelo)
• Portability: Built-in battery supports extended play without cables but consider if you need extra charging options for frequent travel

Usage recommendations

Use the Millennium eONE on a flat, stable table to ensure reliable sensor detection. Keep the board's firmware and your chess app updated for best compatibility. For long sessions, keep a charging cable available to minimize downtime. When transporting, store pieces securely to prevent movement that could stress sensors.
