The MAX31850 is already supported in the 3B family of devices. I rigged up
a test jig with the development board available from Maxim and it worked
fine, however it doesn't support the full (default) 12 bit resolution of
other temperature devices, and as a result reads will fail unless a lower
resolution is specified. I don't remember off hand how high you can go in
resolution value.
Another disadvantage is that you can't distinguish the device type from
the family code ( or anything else as far as I know), so you can't
programmatically tell the difference between the 3B devices which have
on-board EPROM, and those that don't. For my purposes this doesn't matter
very much, but it is unfortunate that more identification capability isn't
built into these devices.

WatchGuard Dimension instantly turns raw network data into actionable
security intelligence. It gives you real-time visual feedback on key
security issues and trends. Skip the complicated setup - simply import
a virtual appliance and go from zero to informed in seconds.
