Sailboats are expensive. If you own an older boat, it is mainly the accessories.
The Raspberry PI mini computer is cheap and powerful. With some extra hardware, it can take over several tasks on a boat, like acting as a wireless access point, proving the plotter charts and software, collecting AIS information or multiplexing NMEA 0183 data.

My main goal is to build a cheap AIS access point as I am using my tablet as the main plotter but I want to get AIS data in, wirelessly.
But as I did start with it, I also investigated OpenPlotter, OpenCPN and other software packages.

So, I decided to share the outcome as there is not much available on YoutTube so far and it was sometimes tricky to find the necessary information.

This is part #1: Hard- and Software Overview

We will take a look at the Wegmatt dAISy HAT PCB on a Raspberry PI 4. We assemble both with a 3D-print housing from "The Pi Hut".
We are going to use a special PCB to convert 12V to 5V providing 3As to run our PI 4.

I will explain the purpose of OpenPlotter, OpenCPN and Kplex and what version of Rasbian we need to install.

This introduction will lead to our #2 tutorial: We will install Rasbian Lite, Kplex and create an wireless access point to send NMEA 0183 AIS data to NC charts, running on normal Android tablet.


Let's go!
