I’ve made Bareboat Necessities (BBN) Marine OS for CoreMP135 from m5stack.

It’s free and open source system based on Debian Bookworm.

CoreMP135 of BBN OS version includes:

• SignalK
• PyPilot
• GPSd
• Kplex
• Canboat
• Victron WEB UI

BBN OS on CoreMP135 turns it into boat appliance able to communicate with N2K, NMEA 0183, PyPilot motor controller and IMU, Victron Cerbo MQTT.

The CoreMP135 device loaded with BBN OS is practically plug and play. After initial boot you can just wire your boat devices via RS-485 or CAN and start using it. No configuration required.

The documentation, source code and download links:

It would help if m5stack sensors could be
put into waterproof enclosures to be used in real world field applications.

The touchscreen product also need some mounting ways to flush mount to panels.

Thanks

Re: Call for articles with your product on M5Stack!!

M5Stack Tough (ESP-32) Sailing Instruments Display and Autopilot Control

M5Stack Tough (ESP-32) Sailing Instruments Display and Autopilot Control Arduino sketches

With LVGL UI

Mostly oriented for boating projects (can be interesting to RV and off-grid living users, or Arduino and esp32 or other microcontroller enthusiasts and hobbyists)

https://github.com/bareboat-necessities/bbn-m5stack-tough

Add housing for all sensors and MPUs to be used in outdoor environment.
Glands, rigged housing, easier wall mounting.
Also can you get rid of rattling and shaking of connected components?
i2c sensors connected to T connectors all move. T connectors for i2c don't even have a hole to screw then in stationary.
Hopefully you can make it Lego like to assemble, or at least IKEA like easy.

Thanks

I wrote code which seems gives 9-axis including magnetometer

Announcing availability of Bareboat Necessities Sensors Hub 1.0.1. It allows connecting various i2c and 1-wire boat sensors to a single m5stack atomS3-lite esp32. No soldering required. Sensors are recognized automatically. Firmware is precompiled and loaded using simple script from BBN OS.

Thanks

Please add solution to support 9-bit UART.
It’s commonly used in SeaTalk protocol.

Thanks

I've made some examples with LVGL and M5Stack Tough.
They are for Arduino.

Somehow I can't make bluetooth to work on it.

Thanks

BBN Boat Sensors

NMEA XDR sensors: lightning strike detector, barometer, humidity, temperatures, illuminance, motion, tank liquid levels, voltage, current, power, water quality and more. Easy to put together DIY. Easy access for maintenance. Affordable and common components. Free and open source software.

Fair Winds!

The latest image now has flutter-ui boatinstrument interface on hdmi port.

SignalK is available via web ui. As well as FreeboardSK and KIP dashboard.

After two reboots SD card partition is resized to max available space.

NMEA 2000 interface is ready. All you need to do is connect two wires.

Most of USB gps devices are recognized on plugging in automatically.

Image includes Victron Web UI as well.

Console access is available via USB-C port at
115200 bauds.

Thanks!

@proTartareSauce

m5stack code for calibration is very primitive. It doesn’t do sphere fit. That’s the issue I had

@mgrouch

I ended up making my own

@teastain

I can’t buy m5stack version of i2c extender because it doesn’t exist.

@teastain

What can I do with that? Thermocouple is for measuring higher temperatures. This thing is plastic.

Thermocouple for measuring exhaust temperature of a car engine looks quite different.

Add MCP9600 I2C Thermocouple Amplifier - K, J, T, N, S, E, B and R Type T

Thanks

Add i2c range extender LTC4311

Thanks

Add 1-wire to i2c unit to connect multiple Dallas Temperature DS18B20 probes

Thanks

Add Lightning Detector AS3935 to your product line.

Thanks
