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.
