Previously all my work on OpenPlotter was done on an RPi3B+ installed in a PI-TOP3 development Laptop that featured a screen, keyboard, and proto board connected to the GPIO (Ref.1-Ref.10). I started with the basic installation, OpenCPN with GPS, OpenCPN with GPS & AIS, Marine Weather on GQRX, Sensors for Temp/Pres/Pitch/Heel/Compass Bearing and GRIB weather files. This project features OpenPlotter Basic/Headless on an RPi4 with all the features as before, but additionally with a WiFi hotspot so I can control the unit from an iPhone or laptop remotely. Figure 1 shows the benchtop test confiuration with the RPi4 with OpenPlotter Basic/Headless, GPS, AIS & GY-91 sensor board. Power supplied by a Portable 80W lithium battery pack. USB power draw as measured with the USB power meter was 5VDC at 1.4Amp.
