+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.
+
+This board was designed using lepton-eda and pcb-rnd.
+
+Here are pdf snapshots of the design for Production PCB version 3.0, along
+with a bill of materials:
