Safe Power Down
#7
I saw a similar schematic but the user had redefined the location of the diodes that makes the voltage drop less of an issue.  see attached schematic.  on their schematic they had used 1 voltage regulator to go to 5v and were using resistors from 12V to 3.3V for pin signaling - I think this may be an issue because the boat battery voltage could vary to much and cause over voltage or early drop outs.  thoughts?
