(successor of “Moitessier HAT”)
The Moitessier HAT 2 is a Raspberry Pi compatible Hardware (“Attached on Top”). Designed for plug-and-play compatibility with OpenPlotter system, it features a 2-channel and high sensitive AIS receiver, a GNSS receiver and even more.
The new Moitessier HAT 2 features a shutdown button
You may now safely shutdown your OpenPlotter / Raspbian OS via this the Moitessier HAT 2 shutdown switch. This will prevent your SD card image from crashing when turning off your Pi with power-off only.
Improved Thermal Control
Increased spacing between Pi and HAT leaves enough room for cooling kits. Hot air is circulated and moved more easily.
Pin header (shown in red on image) and larger standoffs are included with your Moitessier HAT 2 package.
Navigate with OpenPlotter
OpenPlotter makes an integrated Open-Source chart-plotter and navigation platform running on a Raspberry Pi. It is based on the well-known OpenCPN software. You may use OpenPlotter in a headless mode as well – access OpenPlotter desktop from the cockpit through your mobile devices.
We provide ready-to-install .deb packages for major kernel releases of Raspbian Buster. Please, select the package that fits to your kernel version.
Installation via Command Line
sudo dpkg -i package_name.deb
Current Moitessier Driver Version: 1.8.1. See release notes.
Raspbian Buster on Raspberry Pi 3 and Pi 4
We have put together the kernel drivers for Raspberry Pi 3 and Pi 4 into one versatile package. Now, you can install the same package on either systems.
