+description: |
+  MSA311 is a tri-axial, low-g accelerometer with I2C digital output for
+  sensitivity consumer applications. It has dynamical user selectable full
+  scales range of +-2g/+-4g/+-8g/+-16g and allows acceleration measurements
+  with output data rates from 1Hz to 1000Hz.
+  Datasheet can be found at following URL
+  https://cdn-shop.adafruit.com/product-files/5309/MSA311-V1.1-ENG.pdf
