Thanks Ironman

So the difference between pulling wires from the rs232 Tx and rx pins vs using the gpio rxd and txd pins is 3.3v vs 5v... lame

What about getting a rs232 to microusb and working that with the ESP32 - I guess that would work using the serial print command - or will I still need some sort galvanic isolation?

By the way - I assume Tx goes to NMEA- correct?
