I'm going to use the car battery with a DC to DC converter to power the OrangePI at all time, the lcd screen will be powered when the ignition turns on.
Maybe, if possible, when the OPI receive a "ignition on" signal it will show a welcome screen for a few seconds before going to the main 7 gauge cluster?
