I've been working on something like that for M5Stack. It takes NMEA 0183 via MQTT wirelessly and displays it on the M5Stack display. Mine is intended for the nav station, so size and sunlight readability aren't as important. This is a development of one that I put together previously for a 4 x 20 line LCD display, which I am using now. RIght now it displays Location, speed, course and wind data. If I have enough memory, I intend to add Engine and Electrical data, as well as depth. Since the M5Stack accommodates an SD card, it should be possible to store historical data as well, but again, it's all about program memory right now.
Here's the Github: https://github.com/andyrbarrow/MQTTNMEADisplay
Still early days, but It works on the bench. It might be possible to port this to something with a larger display.
