OPENCHESSBOARD-PCB (with Arduino Nano ESP32)

The OPENCHESSBOARD-PCB is a 32 cm x 32 cm (12.6 in x 12.6 in) 2-Layer circuit board which contains

– 64 sensors for piece detection (works for magnetic chess pieces)

– 64 x 4 LEDs for highlighting squares and indicate moves

– high-speed multiplexing circuit to reduce the required input and outputs of the micro-controller

– 5 screw-holes for easy mounting

– super slim PCB design (< 10 mm, including Arduino)

This PCB matches directly the size of the chess board which can be placed on top of the circuit board as a semi-transparent playing surface. The Arduino Nano ESP32 is already soldered directly onto the board and the OPENCHESSBOARD is ready to be programmed.

The software is open-source and ready to connect the board to your Lichess account.
