About Scadys

Scadys designs marine electronics for NMEA 2000 and legacy serial protocol networks. For enquiries and contact information, see the Contact page.

The "test vessel"

Throughout these docs the phrase "test vessel" refers to the live sailing platform that Scadys uses as the primary in-service test bed for its hardware. The vessel carries the prototype boards on its NMEA 2000 backbone, sees real masthead transducers, real cable runs, real marine RF environment, real temperature and humidity cycles. Pages labelled "in service — test vessel" describe hardware that is currently mounted on this platform and accumulating sea miles. The vessel is intentionally not named — what matters here is the operating environment, not the boat.

How this documentation is made

The technical content on this site — circuit descriptions, component tables, design calculations, PCB layout notes, and verification checklists — is generated and maintained using AI assistance (Claude by Anthropic), working directly from KiCAD schematics and PCB files as the authoritative source.

All AI-generated content is reviewed by the hardware design team before publication. Where values are calculated or inferred rather than directly measured on hardware, they are labelled as such.

Always verify critical values (voltage thresholds, current limits, timing margins) against the source schematics and datasheets before using them in a design.
