STEVAL-MKI015V1
adapter board for the LIS344ALH
Introduction
The STEVAL-MKI015V1is an adapter board designed to facilitate the evaluation of the
LIS344ALH three-axis analog output linear accelerometer. The board offers an effective
solution for fast system prototyping and device evaluation directly within the user’s own
application.
The STEVAL-MKI015V1 can be plugged into a standard DIL 24 socket. The adapter
provides the complete LIS344ALH pinout and comes ready-to-use with the required
decoupling capacitors on the Vdd power supply line.
The pinout of the adapter is fully compatible with all other available adapter boards, making
it possible to switch from one sensor to another easily during device evaluation without the
need for board redesign.
This user manual provides information on the STEVAL-MKI015V1 only. For details
regarding the LIS344ALH specifications, please refer to the datasheet for the device.
