+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
