STEVAL-MKI021V1
MEMS 3-axis ± 2g analog-output demonstration board
based on the nano accelerometer LIS331AL
Data brief
Features
■ 3-axis, ±2g motion sensor with analog output
■ embedded self-test
■ high shock survivability (up to 10000g per 0.1
sec)
■ RoHS compliant
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.
