How to connect NMEA0183 to rpi
I'm looking to link a lowrance link-6 s to a raspberry pi running openplotter so that I can use the GPS coords with OpenCPN.
The radio has 6 wires (2 speaker, 4 NMEA) in a single connector that I've not seen before. Is that a standard connector? how do I link it to the raspberry pi?

Waveshare's isolated 2-ch RS485 HAT is the thing you want.
