Marine instrumentation

One small system.
Every instrument in view.

Sail Irons connects NMEA 2000, Nexus, sensors and local displays through multi-board ESP32 firmware. Data remains aboard and is presented through a browser-based instrument interface.

Platform

A bridge, instrument server and diagnostic surface.

The firmware observes the marine network, derives selected values when source data permits, and serves a responsive interface directly from the vessel.

01

Network integration

NMEA 2000 CAN and the legacy Nexus Network share one data model. Source precedence and unavailable states remain explicit.

02

Local instruments

Sailing, engine, electrical, GNSS, compass and diagnostic pages run from the node without an external service.

03

Hardware profiles

Board-specific pin maps and capability flags adapt one firmware codebase to sailing displays and DIN-rail I/O nodes.

Hardware profiles

Current and planned boards.

Release-tagged profiles are available through the installer. LILYGO profiles are listed separately while board-specific artifacts and physical bench acceptance remain pending.

First provisioning

From sealed board to running node, in a browser.

The installer writes a release-pinned factory image and its matching local interface over USB. No development toolchain is required.
