Just a thought, I would have mounted the exhaust fan toward the top of the cabinet. Reason being, hot air rises, and with the fans across from each other the air will likely pass straight through and not accomplish heat relief or humidity control. The box may be small enough not to matter but, for whatever it is worth. Cool project.
I think you could have just added an out-flow fan at the bottom on the box and maybe a dust mesh on the sides. I'm not sure if rain will be hitting your box, but the side fan may suck some water in, including dust. Overall, I would still advise adding some dust mesh covers between fans and the box, it can also stop bugs and spiders from trying to get inside it. Awesome project man, I don't even have a boat but I like random projects like this. lol
LTE modem on that router has gps and probably place for external gps antenna. So I would use this router as gps too. It’s OpenWRT router and you can install gpsd and KPlex on it. I would pack it to same box a small Ethernet switch to have more Ethernet ports. Also the router has usb port. Might be possible to connect NMEA 0183 to usb converter and get NMEA 0183 or AIS data into router and multiplex it using KPlex. This way without pi you can access plenty of data from the router. It’s less power consuming than pi.
@@TheFloridaCaptain I have same router onboard for several years. I use it as gps with external antenna. LTE modem on it has gps chip and I made a small hole for antenna wire. There is micro connector for external gps antenna on the LTE modem. I configured KPlex to read it. KPlex is installable on OpenWrt as additional package. I’m thinking about moving dASIy AIS usb from pi to router to have AIS data even with pi powered off.
I’m currently sailing with open cpn on a Pi 5, and Navionics that costs me $80/yr for my phone or tablet hotspots to my phone, my tablet is lte it uses the gps chip download the charts when you have internet offshore use saved maps and gps only no other connection
