sarfata/kbox-firmware: Open-source electronics for your boat
- Buy KBox on Tindie!
Thanks for your interest in KBox! As of May 2020, I am not manufacturing or selling KBox anymore. All the source code and design files remain available for your inspiration and if you have any question, feel free to reach out by twitter message, email or via a github issue.
You might also be interested in my new project, inspired by KBox: a better sailing analytics platform. So if you are looking for a way to improve your tacks, perfect your downind sailing or just measure sailing angles and speeds, head over to ChartedSails.com.
KBox connects your boat networks together and translates message from one bus to the other. KBox also includes multiple sensors that publish information on your boat networks. Finally KBox has a screen that can be used to repeat some of your boat parameters.
Of course KBox is designed with the SignalK specification in mind and will be compatible with it.
KBox hardware includes:
- One NMEA2000 interface,
- Two NMEA0183 inputs (one of them can be used as a Seatalk input),
- Two NMEA0183 outputs,
- One WiFi interface that can connect to an existing network or create a new network on your boat,
- Three analog inputs to measure voltages between 0 and 23V (batteries, solar panels, generators, etc),
- One shunt input to measure current consumption of your main house battery,
- One barometer,
- One inertial measurement unit providing a magnetic compass, an accelerometer to measure roll, pitch and yaw as well as a gyroscope,
- An SDCard to record data.
KBox is an open-source hardware project. You can review the schematics and build it yourself. You can also order a fully assembled and tested KBox from tindie. Every KBox sold via tindie helps support the project. Thank you!
Find more news about KBox on hackaday.io.
You can now order KBox on tindie.com. Supply is limited so use the "Join Waitlist" button to help me figure out how many I need to order and build.
We are still working hard on the software but we anticipate that the first and most useful use-cases will be:
- Relay GPS and AIS information to your mobile devices (for example, an iPad running iNavX).
- Monitor your energy and display voltages and currents on your existing NMEA2000 equipment
- Record your boat position, and all its parameters (speed over ground, speed over water, heeling angle, apparent and true wind, etc) to an SDCard to replay the race at a later point.
Because KBox is open-source, you can do a lot more things with it:
- Use KBox as a basic NMEA2000 to USB or Network gateway (for example, for SignalK development)
- Build an open-source autopilot and use KBox hardware as the main sensor and computer (we have extension ports to connect to the actuator)
- etc ...
As of September 2018, the KBox firmware:
- General functionality
- Creates a new WiFi network (KBox) or can join an existing network (via simple code modification and recompiling)
- Supports up to 8 simultaneous TCP clients connected on port 10110
- Integrated web server
- Configuration via a config file on the SDCard (see
extras/config for examples
- NMEA0183
- Forwards all NMEA0183 sentences to WiFi clients via TCP
- Converts RMC (GPS speed and coordinates) and MWV (Wind) to SignalK
- NMEA2000
- Forwards all NMEA2000 messages to WiFi (even the ones not understood by KBox) in Seasmart format (they look like NMEA sentences and start with
$PCDIN)
- Converts PGN 127245 (Rudder), 127250 (heading), 128259 (boat speed), 128267 (depth), 129025 (position rapid lat/lon), 129026 (sog/cog rapid) and 130306 (wind speed and angle/direction) to SignalK
- Generates PGN 127508 (battery), 130310 (baro pressure), 130306 (wind), 127257 (attitude), 127250 (magnetic heading), 129026 (sog/cog rapid) from SignalK
- Sensors
- Measure nmea2000 bus voltage as well as all three battery banks voltage.
- Measure barometric pressure
- Measure roll, pitch and magnetic heading
- Sensor data is available in SignalK and is automatically converted to the relevant NMEA and NMEA2000 messages
- SignalK:
- All updates generated from NMEA, NMEA2000 and internal sensors are available over websocket
- Data logging
- All NMEA and NMEA2000 messages are logged to the SDCard
- Display
- Battery monitor page: shows voltages of all battery
- Stats page: shows number of received and transmitted messages on all interfaces

KBox is based on the Teensy 3.2 architecture and is compatible with the Arduino development environment. The WiFi module is an ESP8266-13 and is also programmed with an Arduino compatible SDK.
This project contains the source code for the firmware running on the host micro-controller (teensy-like Cortex M4 micro-controller) and the firmware running on the WiFi module.

-
2018 09 07 - v1.3.6
- Force ESP board definition to generic module w 1MB flash to avoid build error.
- Upgrade ESP platform to 1.8.0 to use ESP8266 framework 2.4.2 which improves stability of the WiFi modules and seems to fix a number of connection issues for other people. Hopefully will also improve KBox wifi stability.
- Add HTTP CORS header on
/signalk. This makes KBox compatible with the amazing Kip to display your boat data in a browser.
- Fixed a typo in the reboot reasons.
- Add missing dependency
pyserial in the list of dependencies for kbox.py.
-
2018 07 26 - v1.3.5
- Fix a bug that would cause KBox to crash on NMEA sentences without a checksum
- Fix a bug where RMC sentence without a date would crash KBox
- Added support for parsing DPT and DBT NMEA sentences
- Added support for generating DBT and DPT sentences. By default only DPT is enabled.
- Added support for parsing XDR air temperature measurements.
- Parse magnetic variation from RMC sentence

-
2018 07 06 - v1.3.3
-
Fix a bug which forced us to use program-esp to update the wifi module. It is now possible again to just use the following commands to update KBox:
platform run -e host -t upload
platformio run -e esp -t upload
-
Change default esp upload speed to 921600 because 2000000 does not seem well supported on Windows.
-
Changed the 'end of programming' detection method to more reliably detect when we are done programming and reboot KBox.
-
Tested the official ESP uploader on Windows and OS X. Comment out the line tools/platformio_cfg_esp.py in platformio.ini to use it. It will be a little bit slower but might work better for some people.
-
2018 07 06 - v1.3.2
- Changes to the build configuration to improve compatibility with Windows and address breaking changes in plaformio.
- Fix some issues that prevented the tests and sktool from compiling on Windows.
- Also added automatic builds on AppVeyor with Windows to hopefully detect Windows issues sooner in the future.
-
2018 05 26 - v1.3.1
- Fix bug which prevented WiFiRXError from being displayed on stats page.
- Fix bug in
kbox.py tool send wifi config command.
-
2018 05 18 - v1.3.0
-
New logfile format, compatible with SignalK server, saves NMEA messages, NMEA2000 messages and SignalK messages.
-
KBox will get the date from NMEA or NMEA2000 and display it on the screen.
-
KBox will wait until it knows the current time to start logging (this can be changed via configuration)
-
Log files are named after date and time of their creation
-
KBox will save in the logfile important system messages and some stats
-
Bunch of new configuration options:
"logging": {
"enabled": true,
"logWithoutTime": false,
"logNMEA2000": true,
"logNMEA": true,
"logSignalK": true,
"logSystemMessages": true,
"logSignalKGeneratedFromNMEA": false,
"logSignalKGeneratedFromNMEA2000": false,
"logSignalKGeneratedByKBoxSensors": true
},
-
KBox will print version number and time on the "StatsPage"
-
StatsPage is the new default page
-
-
