-Compared with the v1 series, v2 includes a better GPS (uBlox vs
-Skytraq), higher power radio (40mW instead of 10mW), wider range and
-more precise pressure sensor (100k' MSL vs 45k' MSL), larger on-board
-storage (8MB vs 2MB), more precise, wider range accelerometer (12 bits instead of
-10 bits, 105g instead of 70g) and faster processor (32-bit ARM instead
-of 8-bit 8051).

+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 ##
-
-Prototypes of v2.0 were flown at Airfest 2013 and everything worked
-great, except that we're not satisfied with the performance of the GPS
-antenna chosen.  We hope to resolve that issue soon and should have
-TeleMetrum v2.0 boards for sale shortly.
