STEVAL-MKI016V1

STEVAL-MKI016V1 Demonstration board based on the LIS344AL Data brief Features ■ Self-test signals through the use of a jumper ■ RoHS compliant ) s ( ct Description The STEVAL-MKI016V1 demonstration board is designed to provide the user with a complete, ready-to-use platform for the evaluation of the LIS344AL. The LIS344AL 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 noninverting buffer, making both direct sensor outputs and buffered sensor outputs available to the user. ) (s u d o r P e s b O t e l o STEVAL-MKI016V1 t c u d o r The STEVAL-MKI016V1 also provides an easy way to control the self-test pin.
