+Compared with v2 series, v3 includes a better GPS (uBlox v8 vs v7),
+the TI CC1200 radio used in our other products instead of the CC1120
+used only in TeleMetrum v2 (more or less the same performance, but one less
+device driver for us to have to worry about!), and more accelerometer 
+range with approximately the same precision.

-## Future Plans ##
-
-Our inventory of TeleMetrum v1.2 boards was lost in the fire that destroyed
-Bdale's home in June 2013.  Work is progressing on "TeleMetrum 2.0" which will
-be connector placement and screw hole compatible with previous boards, but
-built with entirely new circuitry.  Better sensors, better processor, better
-GPS, better radios, etc.  Prototypes were flown at Airfest and everything
-worked great, except that we're not satisfied with the performance of the 
-GPS antenna chosen.  We hope to resolve that issue in time to have TeleMetrum
-v2.0 boards for sale by the end of November 2013.
