NMEA 2000 Powered Computer System With Raspberry Pi 4, NMEA 2000 HAT, Pre-Installed OpenPlotter And Signal K

Posted by Wilfried Voss on

Metal Enclosure for PICAN-M and Raspberry Pi 4

Copperhill Technologies offers various  NMEA 2000 compatible embedded systems, including HATs for the Raspberry Pi and the Arduino-compatible line of Teensy modules.

The NMEA 2000 standard defines a low-cost, modest capacity, bi-directional, multi-transmitter, multi-receiver instrument network. The hardware layer utilizes the CAN (Controller Area Network) technology. Typical data on an NMEA 2000 network include:

  • Position latitude and longitude
  • GPS status
  • Steering commands to autopilots
  • Waypoint lists
  • Wind sensor data
  • Engine sensor data
  • Depth sounder sensor data
  • Battery status data
  • And more...

However, the Raspberry Pi offers the most significant potential when it comes to creating a full NMEA 2000 and NMEA 0183 compatible embedded system because the line of products includes the Raspberry Pi HAT, a metal enclosure, and a Micro SD card with a pre-installed operating system plus OpenPlotter and Signal K.


OpenPlotter is a combination of software and hardware to be used as a navigational aid on small and medium boats. It is also a complete home automation system onboard. It works on ARM computers like the Raspberry Pi or any computer running a Linux Debian derivative. It is low-cost, low-consumption, and modular. You will need the basic parts and some optional parts. It will depend on what kind of data you want to collect, process, display, and what type of equipment your boat already has. More Information...

Signal K

Signal K is a modern and open data format for marine use. Built on standard web technologies, including JSON, WebSockets, and HTTP, Signal K provides a method for sharing information in a way that is friendly to WiFi, cellphones, tablets, and the Internet. A format available to everyone, where anyone can contribute, Signal K is the first truly open data format for the marine industry. It is set to revolutionize how we consume and interact with data on boats. Signal K is open source, but friendly to companies that want to use it in closed source applications or hardware.

Advanced Marine Electrics and Electronics Troubleshooting: A Manual for Boatowners and Marine TechniciansAdvanced Marine Electrics and Electronics Troubleshooting

Whether you are a marine electronics professional or a boat owner, Advanced Marine Electrics and Electronics Troubleshooting helps you understand the new, more powerful methods of troubleshooting marine electrical and electronic systems.

A modern boat’s sophisticated installations and networked electronics can stretch the traditional diagnostic methods based on trouble lights and multimeters past their useful limits. 

This book will show you how to:

  • Use microprocessor-based diagnostic tools and techniques from the automotive and communications sectors, adapted for boats for the first time
  • Diagnose the most difficult AC and DC problems
  • Protect communications and navigation electronics from interference and lightning
  • Seek out and eliminate stray-current sources and galvanic corrosion
