UM0537 User manual STEVAL-MKI019V1 demonstration kit for the LIS302SG Introduction The STEVAL-MKI019V1 is a demonstration kit designed to provide the user with a complete, ready-to-use platform for the evaluation of the LIS302SG. The LIS302SG 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 control the Power-down and Self-test pins.
