Electronic chessboards sense changes in piece positions and send that information to an app or computer. Compatible software then updates the online game. The exact sensing method, required chess pieces, connection options, and supported platforms depend on the board model.
How an electronic chessboard detects a move
When you move a piece, the board detects a change in the position on its squares. Depending on the model, it may register occupied squares, identify pieces, or report the position in another format. The board passes that information to connected software, which interprets it as a position or move.

The sensing method is not universal. DGT says its Bluetooth e-Board uses electromagnetic resonance with its electronic pieces, called e-Pieces. That description applies to this DGT board, not necessarily to other electronic boards. DGT Bluetooth e-Board User Manual
How the board syncs moves to an online game
The board sends position or move information through a supported connection to an app or computer. That software maintains the digital game state and communicates with the online chess service. In other words, the board detects the physical change; the compatible software handles the online connection.

Chessnut’s eBoards API documents a Bluetooth Low Energy (BLE) service with a position-notification channel and a command for real-time FEN reporting. FEN, or Forsyth–Edwards Notation, represents a chess position. This is one manufacturer’s documented interface, not a standard shared by every electronic board. Chessnut eBoards API documentation
DGT documents USB and Bluetooth connections for its Bluetooth e-Board, with only one communication option usable at a time. Chessnut says its Move board connects through the Chessnut app to Chess.com, Lichess, and other major platforms. These are model-specific manufacturer claims; confirm current support and setup requirements for the exact board, app, firmware, and service you plan to use.

What to check before choosing or connecting a board
- What it detects: Check the exact model’s documentation to see whether it reports square occupancy, piece identity, or another representation.
- Which pieces it requires: DGT says its Bluetooth e-Board requires an electronic chess set and lists compatible DGT e-Pieces. Do not assume ordinary pieces or a third-party set will work; check the board manual.
- How it connects: Verify whether the model supports USB, Bluetooth, or another connection, and whether your device and operating system are supported.
- Which app and platforms it supports: Confirm the complete connection path to your chosen online service. Support for one board does not establish support for another.
- How opponent moves appear: Some setups show the online opponent’s move for you to play on the physical board. Chessnut describes automatic opponent-piece movement on Move; verify this feature for the specific model rather than assuming all boards move pieces automatically.
Why a move may not register or sync
Start by checking that the physical position is correctly registered and the board is connected to the intended app. Then verify that you are using the required pieces and that the board, app, and online service support the setup you selected.
