The website with the image was down for a while, but I finally got it. Had trouble with the 64bit version (Authorization error(?)). Did get the 32-bit version to load.

What devices are recommended for the Signal-K portion? I have some discrete sensors, (I was going to try to do something like that before) will they work if hooked to the appropriate GPIO pins?

When I did the sudo apt update I got errors that the lys-whatever was an unknown source.

Some gpio connected sensors are supported usually via SignalK plugins.

PyPilot will recognize supported IMUs.


See supported hardware section.

Latest BBN OS is 64-bit kernel and 32-bit user spaces.

The warnings you get on apt-get update are normal. You can ignore them they are harmless.

Is there a basic hardware list somewhere? I want to know what I need to get this all working.

Raspberry Pi4
BerryGPS-IMU GPS and 10DOF

What else? How do I connect it to the NMEA2000 network? (WiFi is unavailable while underway.)

Yes. There is whole supported hardware list in getting started guide.

I saw the 'supported hardware list' when I first started playing with this. Can't find it again, but that is not what I'm asking. I want to know the minimum hardware/software I need to connect the Pi to my NMEA 2000 network directly as my WiFi does not operate when I'm not at the dock.

Your local WiFi hotspot is available all the time. If you haven’t removed your hotspot which was enabled by default. You could set up your NMEA 2000 WiFi multiplexer to use it and then create connection from SignalK to it.

If you do not have WiFi multiplexer then you need CAN adapter. There are usb options there are hat options or usb or WiFi or Ethernet multiplexers.

All the software is already installed for either option. Your data entry point would be SignalK.

NMEA 2000 is CANBus. So you can search for CAN to USB converters. Canable starts with $23.

Many boards for raspberry pi CM4 already have CAN interface so no additional hardware is needed for those.

You just need to connect your IMU 10dof and pypilot should recognize it. So only connecting is required. No set up on pi is needed.


If it has some pressure or temp sensors then you need to set up their address in SignalK plugin (depending of what sensor you have)

Has anyone used this sw with the moitessier hat? How to configure the connection for gps, ais from this hat without openplotter?

Look at the sources here

https://github.com/openplotter/openp...tterMoitessier

It installs driver via dpkg
it loads driver as kernel module
it does something to udev rules
then there is /dev/moitessier device
I think it is serial port. You use it just as any other serial port. Make a connection in SignalK to it. Baudrate check when it’s set to in the code from above link.
pressure and temp is probably read via i2c.

* Canable seems to be unavailable since quite some time (openlightlabs says: sold out, price would be 29 or 60 $ for isolated USB)

* Maybe the TouCAN adapter would be a nice (but a bit pricey) option? It was unavailable a month ago but the website (https://www.rusoku.com) now says: available. The marine version (isolated) costs 95 € (https://www.rusoku.com/shop/toucan_marine). Looks very professional and when I inquired availability a month ago I got immediately an answer.

There are way more options

https://bareboat-necessities.github....l#_nmea_2000_2

And there are many CM4 boards which come with CAN

Yes, I am aware of your excellent list of hardware. Thank you!

This said, TouCAN compares favorably imho and could/should be added to the list. -- If one needs a logger only, the products from CSS electronics (https://www.csselectronics.com/pages...dware-products) seem also "add-worthy".
