Moitessier HAT 2 for Raspberry Pi 4, and RPi 3
(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.

High-sensitivity dual channel AIS receiver with SMA antenna connector
Sensitivity: -112 dBm min.
High-performance GNSS receiver
Integrated patch antenna plus support for external antenna via BNC connector

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.

Standalone usage or in combination with Raspberry Pi
Fully compatible with Raspberry Pi models supporting 40-pin IO header
3 status LEDs
AIS status, GNSS status, Error

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.
