User manual
STEVAL-MKI014V1
demonstration kit for the LIS344ALH
Introduction
The STEVAL-MKI014V1 is a demonstration kit designed to provide the user with a
complete, ready-to-use platform for the evaluation of the LIS344ALH. The LIS344ALH is a
low-power 3-axis linear capacitive accelerometer that 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 way to select among the two Full-scales allowed by the device,
and to control its Power-down, Full-scale and Self-test pins.
