It is a remote terminal to have all the information of the OpenPlotter system that is installed in the cabin of the sailboat
The display is from SHINHO Electronic Technology (China), 7 "resistive touchscreen, 1.000 nits, 12 V supply, and waterproof (194 USD at origin; I bought it directly). HDMI input. Brightness control. (Important, because during night is necessary to reduce at minimum). http://www.sihovision.com/

I use an RPI 3A to connect to the RPI4B openplotter network, which centralizes all NMEA183 instrumentation (GPS, AIS, Wind, Speed, Log, depth, battery monitor, barometer, and IMU compass). Low consumption and enough for this purpose
Load only a simple Raspbian + Chromium + VNC in this Rpi, and set Chromium to start directly in KIP pages
Pi is feed by a 12 to 5v converter from car smartphone charger. (2,5 A)
Use an small Bluetooth keyboard + trackpad for local configuration when needed.
You can run all the information screens of the KIP plugin, and also connect by VNC and have OPENCPN on this screen; including AIS. Final design is a start screen with only two big icons (KIP and OPENCPN)
Actually there is a waterproof pushbutton (+ bi-stable relay) for on / off. But I will modify to start and shutdown Rpi via GPIO. (much more secure for the Micro SD)
