First, a few important notes that you should definitely observe.<\/strong><\/em><\/a><\/span><\/p>\n

Often the task with older boats is to connect different sensor networks with each other and to exchange data between the buses such as NMEA0183 and NMEA2000. In addition, you would like to transfer the data via WiFi and see it on a tablet or make it available to a navigation app. For this purpose, there are so-called gateways or WiFi gateways in the commercial sector that solve such tasks. There is now one free OpenSource implementation for the NMEA2000 bus by Timo Lappaleinen<\/a> that you can use in your own projects. Andreas Koritnik has worked in several Workshops<\/a> in different Projects<\/a> shown how to read and feed data on a NMEA2000 data bus. In his workshop, small electronic modules with an ESP32 and CAN line driver are used which have to be soldered in order to obtain a functioning overall circuit. The projects are not complex. But if you have no soldering experience, you hardly dare to undertake such a project.<\/p>\n

The Chinese company M5Stack<\/a> sells small, ready-made and inexpensive electronic modules for the learning area that can be connected to one another by plugging them together and are mechanically compatible with the Lego world. The M5Stack modules are, so to speak, the electronic counterpart to the mechanical building blocks from Lego. So even people without soldering skills can set up individual electronic circuits and make them usable for themselves. You can get a good overview of all the possibilities of the modular system on the M5Stack website.<\/p>\n

Universal WiFi NMEA gateway<\/h2>\n

Andreas Wellenvogel took up Andreas Koritnik's idea and developed it further with these finished modules Software project on GitHub<\/a> started aiming at a universal WiFi NMEA gateway. The gateway consists of the following basic components:<\/p>\n
