The open-source smart chess board
You can now play directly via the Blichess App: This allows a more feature rich setup via your smartphone. You can use the board to record your moves played on the OPENCHESSBOARD, for example if you are playing against a friend and want to save the game for later analysis. Or use the opening explorer Read More blichess: connect via smartphone
You can now view the schematics and the total PCB design of the OPENCHESSBOARD.
The following image shows the pinout of the OPENCHESSBOARD as example connection based on the Arduino Nano 33 IoT. Different MCUs need to fulfill the requirements shown on the left. Connectivity via WiFi or BLE provided by the Arduino Nano IoT 33 are also required if another MCU is used.
This is an example DIY project for building a smart chess board with the OpenChessBoard hardware for playing on lichess.org. The board consists only of 4 components: OpenChessBoard-PCB Arduino control unit Acrylic glass with wood veneer chess board Wood frame The board directly connects to your account on Lichess.org and finds ongoing games.

Processing unit All the computing power is provided by an Arduino Nano 33 Iot. The total board is powered via micro USB which is also used for programming the board. When using the board on the go, a power bank can be used to power the board. The board uses only 11 digital outputs of Read More How does it work? Take a look under the hood
