My $150 Raspberry Pi Beats a $4,000 Raymarine Chartplotter (OpenPlotter + Signal K)

A $150 Raspberry Pi 5 running OpenPlotter and Signal K does more than our $4,000 Raymarine chartplotter. Here's how we decode NMEA 2000 data for free and build a custom touchscreen boat dashboard for wind, weather, Victron power and JK BMS lithium batteries, plus remote monitoring by text through Telegram. We also explain NMEA 0183 vs NMEA 2000 with an animated side-by-side of how boat data actually moves on the network.
