[time-nuts] M12 furono (also GT-8031)

[Mark Sims]

I got in my prototype Furuno GT-8031 adapter boards in and it is working well.   Lady Heather now works with the GT-8031.

The M12 prototpe adapter boards have shipped from OSHPARK a couple of days ago.  They might get here today.

I have since updated the adapter boards to add a CR2032 backup battery.  Also the GT-8031 board now has H.FL and SMA connectors for connecting an antenna without having to chop up the antenna pigtail on the 8031.   The 2mm and 50 mil headers have not yet arrived from China.
