STEVAL-MKI021V1

MEMS 3-axis ± 2g analog-output demonstration board

based on the nano accelerometer LIS331AL

Description

The STEVAL-MKI021V1 demonstration board is

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 STEVAL-MKI021V1 also provides an easy

mean of controlling the power-down and self-test

pins.
