We now also have a galvanic isolated version of the tiny SeaTalk Nmea Bridge available
Galvanic isolation protects your board computer and your instruments.
Galvanic isolation  is especially interresting if your have different power sources for the board computer and the instruments. I.e. the board computer can be connected to shore power, if you have different batteries for computer and instrumentation.  It also protects your computer and your instruments in case the SeaTalk Nmea Link should accidently be connected with reversed polarity.
It simply makes the whole system more more reliable and safer.
