-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

+TeleMetrum v4 early units shipped with uBlox MAX-M8C GPS modules, but we had
+a low yield on those boards for some reason.  Newer units have the MAX-M10S
