Configured Raspberry Pi 5 + MacArthur HAT Marine Computer
A ready-to-configure open-source marine navigation hub built around Raspberry Pi 5, OpenPlotter, Signal K, OpenCPN, and the MacArthur HAT.
Built around Raspberry Pi 5, OpenPlotter 4, Signal K, OpenCPN, and the MacArthur HAT. Select the storage, network, power, GPS, AIS, sensor, and remote-access options that fit your boat.
Display, charts, AIS antenna, NMEA cabling, sensors, installation, and optional modules are included only when stated in the final configuration.
What the starting configuration includes
- Raspberry Pi 5 computer with appropriate active cooling
- Prepared storage and base operating system
- OpenPlotter, Signal K Server, and OpenCPN installation
- MacArthur HAT configuration for the agreed interfaces
- Initial local network and secure-access setup
- Configuration backup and plain-language connection notes
Available build options
NVMe storage
Faster, more durable primary storage for charts, logs, dashboards, and applications.
Managed 12V power
Optional MacArthur power module for clean start and shutdown behavior when properly installed.
GPS and AIS
Add positioning and compatible AIS hardware based on whether you need reception or transmission.
Boat-data dashboard
Arrange battery, solar, tank, weather, engine, depth, wind, and position data around your actual sources.
Remote support
Secure remote-access setup for updates, troubleshooting, and system checks when internet is available.
Bench configuration
Ship your compatible hardware for software setup or order a complete agreed package.
Before ordering
Prepare a list of your existing chartplotter, GPS, AIS, depth, wind, engine, battery, inverter, solar, and tank equipment. Include connector types, network protocols, photographs, and what you want to see or control. This prevents buying adapters that do not solve the actual problem.
