STEVAL-MKI021V1
demonstration kit for the LIS331AL
Introduction
The STEVAL-MKI021V1 is a demonstration kit designed to provide the user with a
complete, ready-to-use platform for the evaluation of the LIS331AL. The LIS331AL is the
smallest consumer low-power 3-axis linear capacitive accelerometer. It includes a sensing
element and an IC interface capable of taking information from the sensing element and
providing an analog signal to an external application.
In addition to the MEMS sensor, the system includes a linear voltage regulator and a rail-to-
rail low noise quad amplifier configured as a non-inverting buffer, making both direct sensor
outputs and buffered sensor outputs available to the user.
The kit also provides an easy means to control the power-down and self-test pins.
