(This is a continuation of Part 1 and Part 2…)

Wow, it’s been over 7 years since I built my first NMEA2000 Boat Gauge and it’s been working flawlessly ever since.   I recently got into the ESP32 platform (I know very late to the game) and I was interested to see what types of advancements there have been in round LCD screens.  The biggest challenge I had with the 4d systems screen module was it’s not a perfect circle and thus it did not fit within the envelope of the 2″ gauge casing.   That caused all sorts of complications. This is where the 1.28″ screen by Waveshare comes in (available @Amazon).

The screen comes in both touch screen and non-touch screen versions. I have both working, but since my screen will be mounting inside a matching gauge with a lens over it. I will be installing the non-touch screen version and adding the capacitance touch to the metal bezel. That worked great in my current installed version.

Part II: Custom NMEA 2000 2″ Round LCD Multifunction Display Gauge for Boat

The gauge has now been installed since late July 2017 and it’s functioning well.  I was concerned that the sun and heat (and the winter cold) would cause some issues but so far things are working great.   The installation of the display in the  gauge cluster was a bit rough due to the 4d systems screen module is none circular.  I had to design the casing in two parts screen/bezel and rear PCB housing.  Where the two meet up was a weak point and required a few tries.  I’m looking to possible using a new LCD module in my next version as 4d System is discontinuing the ULCD-220RD :).

Here’s a video of the gauge functioning in the boat:
