Smart Catan

A physical board with digital assistance: real tiles and pieces, people around a table, and less bookkeeping between turns.

This wiki explains the seven-hex prototype and the intended path to a 19-hex board. It describes the architecture being developed; examples are design contracts, not evidence of running firmware.

Start here

• Project goals — what the electronics should add to physical play.
• System architecture — how the pieces fit together.
• Seven-hex prototype — layout, chain order, and first integration steps.
• Prototype BOM — quantities and purchasing references.

Area	What you will find
Hardware	Geometry, sensing, power, and prototype wiring
Software	Board mapping, rules, events, and reconciliation
Components	Playable Pieces, Smart Hex, Base Board, Display Unit, and Mobile Web App
Protocols	Hex-to-main communication and future message contracts
Reference	BOM, resistor registry, and glossary
Development	Prototype roadmap, diagnostics, calibration, and open questions

The main controller, pin allocation, resistor assignments, contact design, and wire protocol still need definition. Those limits are explained on the relevant pages and collected in open questions.
