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.

That looks great, thanks for sharing!
do you have any software example?

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.

Matti,

This is excellent. I just built out the NMEA 2000 gateway and programmed it. Works better than my Rusoku Toucan adapter. My devices on connected to SignalK all seem more reliable on it. I’m already having to build extra ones for friends!

Main thing I was interested in it for was to create an engine monitoring device with it. I see you are already building a hat that will do that. Can’t wait. Please post when that is available.

Thanks for all you’ve done.

Great stuff, will buy a couple and outfit friends boats that needs more sensors...

That's absolutely great news! Thanks for sharing!

I've indeed been desigining an engine top hat: https://github.com/hatlabs/SH-ESP32-engine-hat. I've received the first proto batch a week ago but haven't had time to touch them because I've been trying to get the Sailor Hat for Raspberry Pis (https://hatlabs.github.io/sh-rpi/) out of the door. I'll get those shipments finished today and will then test the top hats to see how they fare. Given that it's the first proto batch, it's more likely than not that they contain some fatal faults. But we'll see. I'll let you know.

That reminds me of having to create a new thread for SH-RPi. As soon as I get the first batch shipped.  Big Grin

Yes, I'm checking out the SH-RPI, also. Was thinking to just CAN "straight in" to the RPi using a hat of some sort, instead of a converter. I really like the idea of all the power management features you put on this! Great work! Expect an order for one from me in a couple weeks, when I have more time to tear my Pi setup all down again! Fun stuff!

mairas,

I have a couple of questions on a project I'm working on using SH-ESP32. I've successfully built three N2K gateways, but am moving on to a more difficult (to me) project involving more interfacing and programming. Is there a place I can go to get answers to questions? Or can I just post them here?

Steve
