Power-over-Ethernet magnetometer

PoE magnetometer based on my Calunium microcontroller board (an Arduino clone using the ATmega1284P microcontroller). Included is a GNSS module for time synchronization from GPS/GLONASS/Galileo satellites, USB debugging interface and logic level shifting for interfacing to the remote sensor PCB (see www.flickr.com/photos/stevemarple/8521787269/in/album-721...). The Ethernet interface is provided by an Arduino Ethernet shield (or the later Ethernet2 shield).
