+ * High precision â 2.4Pa resolution (approximately 20cm at sea level)
+ * Factory calibrated.
+ * Analog Devices [ADXL375](https://www.analog.com/en/products/adxl375.html) 3-Axis Digital MEMS Accelerometer

+ * USB serial emulation for "console" interface
+* Tools Used
+ * [Lepton EDA](https://github.com/lepton-eda/lepton-eda) for schematic capture
+ * [pcb-rnd](http://repo.hu/projects/pcb-rnd/) for PCB layout

+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:

+* [schematic](v3.0/telemetrum-sch.pdf)
