UM0532 User manual STEVAL-MKI020V1 adapter board for the LIS302SG Introduction The STEVAL-MKI020V1 is an adapter board designed to facilitate the evaluation of the LIS302SG 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-MKI020V1can be plugged into a standard DIL 24 socket. The adapter provides the complete LIS302SG 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-MKI020V1 only. For details regarding the LIS302SG specifications, please refer to the datasheet for the device.
