SignalK Gateway

A complete marine data acquisition and distribution system based on ESP32 creates a powerful SignalK server that bridges NMEA 0183, NMEA 2000, GPS, and I2C sensors to WiFi-enabled marine apps.

SignalK — A New Generation of Simple, Compact, Reliable Boat Data Networking

ESP32 SignalK is a modern, ultra-compact version of the well-known SignalK marine data server.
Its mission: bring all your boat’s data together in one place, without the frustrations of traditional hardware.

Instead of bulky Raspberry Pis, SD cards that fail, and long setup guides, this device gives you the core power of SignalK in a tiny, plug-and-play form.

Why It’s Better Than a Raspberry Pi Setup

Is the simplest, most reliable, and most compact way to get real-time boat data everywhere — without the hassle of SD cards, operating systems, or complex installations.
