Introducing the new MacArthur HAT

any chance to reconsider and enable isolation or make available optional?

The NMEA 2000 option and power from NMEA 2000 was important to me ... so what I did was use 2 raspi pi:

"Gateway" has NMEA2000 "Pi Can" from SK Pang and runs the main SignalK server.  This box uses the serial port on the PiCan to provide GPS by NMEA0183 to the VHF radio at 4800 baud.

Any device wanting data connects to this "gateway" box ... by either SignalK, or one of the NMEA standards.  This box is the WiFi access point also.


"Sensor provider" box has the Moitessier Hat and nothing else, the purpose of this box is only to provide data to the "Gateway" server ... it was cheaper to do it this way and simple. It provides the GPS, compass, heel, pressure etc from the Moitessier HAT via SignalK to the "gateway" box.
