Sailor Hat with ESP32
#1
Hi all,

Let me introduce Sailor Hat with ESP32 (SH-ESP32). The SH-ESP32 is an ESP32 development board designed specifically for marine use, featuring an integrated 8-32V protected power supply and an integrated NMEA 2000 compatible isolated CAN bus interface. It allows you to create custom sensors and control devices that connect to Signal K and OpenPlotter or directly to NMEA 2000. The board includes opto-coupled signal input and output (one channel each), as well as protected 1-wire and I2C interfaces. There's also a micro USB port for flashing and direct host communication as well as a GPIO header exposing all usable ESP32 GPIOs. Finally, the board includes an ample proto board area for customizations.

Example use cases:
  • NMEA 2000 USB gateways
  • Temperature monitoring
  • Tachometers (RPM meter)
  • Tank level monitoring
  • Relay controlling (lights, blowers, anchor winch)
  • Attitude sensors
  • Electronic compasses
The design is open and available at GitHub. The board documentation is available at GitHub Pages. SH-ESP32 including bundles with enclosures and connectors is available for purchase at hatlabs.fi.

Thanks! SH-ESP32 works as-is with SensESP. There is a reasonable amount of examples available in that repo.

Having said that, I'm right now about to start writing tutorial-type examples for different use cases specifically for SH-ESP32. My plan is to start with an NMEA 2000 gateway example and move on to 1-Wire temperature measurement, RPM meter, tank level measurement etc.

Excellent. Good luck with this project, let me know if you need anything from the OpenPlotter side.

Since NMEA 2000 USB topics have been discussed on this forum before, I'll provide a link to a tutorial I just wrote: it's quite easy to convert the SH-ESP32 into a fully functional N2K USB gateway.
