To do this, I simply connected the NMEA 2000 port to power up the Pi, plugged the included HDMI-mini to HDMI cable into a monitor, connected a keyboard, and followed the install instructions for OpenPlotter/OpenCPN. I installed three different things on the Pi to test with, just for OpenPlotter, OpenCPN, and then just Linux with Signal K. It's not great, but it works for now and keeps the boards reasonably safe. I found a case from HiFiBerry that was meant for an audio HAT and hacked holes in it to allow the NMEA 2000 port to be exposed. I have not found a NMEA 2000 specific case – perhaps an opportunity for 3d printing! Those that accommodate HATs are pretty specific, and have holes or punch outs for specific types of connectors. The standard cases that come with the Raspberry Pi do not assume you will have an add-on or HAT board with it. ![]() This is probably the only downside to this setup. So besides NMEA 20, you can also connect other I2C sensors if you'd like. Compatible with OpenCPN, OpenPlotter, Signal K and CANBoat.Include 3A SMPS to power the board and the Pi from 12v line.Qwiic (I2C) connector for extra sensors.NMEA 0183 (RS422) via 5-way screw terminal.Here's what SK Pang say the board is capable of: The board looks very well built with clearly labeled bits. There is a really nice schematic and user guide that SK Pang have provided on their website. It has a NMEA 0183 terminal block and NMEA 2000 port on the left side in the picture above, and the connector for the Raspberry Pi on the right hand side. The PICAN-M is a pretty simple, yet well designed board. In this case, the extra parts and pieces were important when I bought the Pi to do testing in general, but were not necessary since the PICAN-M provides power, and the case provided by CanaKit won't work. I generally purchase the CanaKit bundle when I am buying a Raspberry Pi (I think I have about 15 right now doing various things at home and on the boat) as they tend to include a nice power supply, case, cables, and mainstream brand SD card, but you can get them cheaper without those pieces if you prefer. I decided to install the PICAN-M on it, and then try out a few different things. I had a Raspberry Pi 4 that I had been playing around with ever since it came out, but didn’t have a clear purpose for it. The original manufacturer of the board is SK Pang Electronics out of the UK. I ordered one from Copperhill Technologies here in the US and it arrived a few days later. ![]() ![]() An easier way….Ī reader and Instagram follower (thanks Ilker Temir!) pointed me to an add-on board, or HAT, for the Raspberry Pi called the PICAN-M, and I was intrigued. #Can a coax gps antenna be connected to a nmea 2000 network plus#Both have pros and cons and require connecting to a USB port on the Pi, plus some configuration. Once the power problem is solved, connecting the Pi to the boat network involved either an Actisense NGT-1 USB adapter ($) or a canable.io adapter to get it on the NMEA 2000 network. I have had good luck with this 12v-5v converter from Tobsun, and I particularly like it because it has four screw down terminals on it, making it easy to connect cabling. I always wanted mine to run off of the 12v DC battery bank without any connection to an AC outlet, inverter, or USB converter that isn't hard wired. Raspberry Pi's run off of USB power which is 5V, and not generally available on the boat in a permanent way. The first step in connecting a Pi to the boat was to find a proper power supply. On sailboats in particular, I loved having a Pi on board because I could have an always-on computer that didn't take a ton of power, had a decent amount of CPU power, and use it to monitor things while I was away. system that has features just like the big vendors. In addition, you can run OpenCPN or OpenPlotter and have a fully functioning boat control, autopilot, chart, etc. #Can a coax gps antenna be connected to a nmea 2000 network software#My main reason is to run a Signal K server on it, have it connected to my NMEA 2000 network, and leverage the hundreds of plugins and pieces of software that you can install to create dashboards, gather data, set alarms and alerts, and so much more. There are many reasons to have a Raspberry Pi connected to your boat network that I can think of. Connecting them to a NMEA 2000 network, and powering them off a DC battery bank has required a bit more work up until now. I’ve had them on every boat since the Pi first came out. Running a Raspberry Pi aboard a boat has been a popular thing to do for a number of years. ![]()
