What is NMEA2000-DISPLAY-on-ESP32S3?

This C-based project turns a cheap Waveshare ESP32-S3 Touch LCD into a full-featured marine instrument display for NMEA2000 networks. It shows wind data, course, SOG, STW, depth, and more, with Raymarine autopilot integration, touchscreen controls, configurable units (knots, m/s), and audible alarms. Built with Arduino IDE and LVGL for the UI, it replaces pricey legacy displays like the Raymarine ST70 without soldering—just plug in an NMEA2000 cable.

Why is it gaining traction?

No custom PCB needed; grab a €35 Waveshare lcd display arduino board with built-in CAN, flash a ready binary via ESPConnect, and you're sailing with a 480x480 touchscreen UI, 3D-printable ST70-compatible housing, and FFAT asset loading for smooth graphics. Autopilot mode switching, alarm acknowledgment, and core 0 tasking for reliable NMEA parsing stand out over basic github lcd i2c shields. Developers dig the plug-and-play setup and SquareLine Studio exports for custom screens.

Who should use this?

DIY boat owners repairing dead Raymarine displays or adding NMEA2000 readouts to helm stations. Sailors wanting affordable wind/course alarms and autopilot controls on a single lcd display 16x2 alternative. Marine tinkerers prototyping with ESP32 and Waveshare lcd who hate soldering.

Verdict

Grab it if you're handy with boats—docs and binaries make setup straightforward despite low 1.0% credibility from 19 stars signaling early maturity. Test indoors first; it's not sun-bright or waterproof yet, but a solid base for github lcd driver tweaks.
