Gambit is an open-source robotic chessboard that moves pieces using magnets and detects their positions with reed switches. It uses a T-Bot mechanism with an electromagnet for precise piece movement and a reed switch matrix for accurate position detection. The board is powered by an Arduino Nano ESP32, which allows for future enhancements like Bluetooth and Wi-Fi connectivity.
- Simple Hardware: Arduino Nano ESP32 with simple components available on Amazon
- Easy Movement: T-Bot mechanism with off-the-shelf parts
- Built-in Chess Engine: Runs a Nibble Chess derived ches engine directly on the ESP32
- Chess Notation Support: FEN, LAN support for compatibility (Working on PGN)
- Modern Development: PlatformIO for better code organization and testing
- Wireless Control: Bluetooth connectivity for app integration
- Affordable: Uses widely available, low-cost components
- Compact: Competition-sized board (approximately 60cm x 60cm)
- Open Source: All designs and code freely available to modify and improve
- Reproducible: Simple enough for hobbyists to build
- Standalone: No external computer required to play
