UM0398 User manual STEVAL-MKI017V1 adapter board for the LIS344AL Introduction The STEVAL-MKI017V1 is an adapter board designed to facilitate the evaluation of the LIS344AL three-axis analog output linear accelerometer. The board offers an effective solution for fast system prototyping and device evaluation directly within the users own application. The STEVAL-MKI017V1 can be plugged into a standard DIL 24 socket. The adapter provides the complete LIS344AL 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-MKI017V1 adapter only. For details regarding the LIS344AL specifications, please refer to the datasheet for the device.
