Print. Click. Play. OpenChess is a fully open source smart chessboard designed to make interactive, intelligent gameplay accessible to everyone. By combining low-cost electronics, 3D printing, and customizable software, OpenChess empowers makers, educators, and chess lovers to build their own connected chess experience — without the high price tag.

💡 Why OpenChess?

Most smart chessboards are expensive and closed-source. OpenChess changes that. It’s built from the ground up to be:

Affordable – Uses a custom PCB with embedded magnetic sensors and LEDs for real-time move detection and feedback.

DIY-Friendly – Print your own board, your own pieces, and assemble everything at home.

Programmable – Based on Arduino, you can customize behavior, create new game modes, or build learning tools and challenges.

Modular & Open – Everything is open source. Remix the board, design your own pieces, or upgrade the electronics however you want.

🔧 What You’ll Need:

OpenChess PCB – Detects pieces and lights up squares.
