STEVAL-MKI004V1

STEVAL-MKI004V1 MEMS 3-axis - ±2g/±6g digital output low voltage linear accelerometer evaluation board based on LIS3LV02DQ Data Brief Features ■ Graphical user interface ■ USB connector ■ Control switches ■ MEMS sensor ■ LED indicators ■ ST7-USB microcontroller Description The STEVAL-MKI004V1 is an evaluation kit designed to provide the user with a complete, ready-to-use platform for evaluation of the LIS3LV02DQ, a low power 3-axis linear accelerometer with digital output. The device includes a sensing element and an IC interface capable of translating information from the sensing element into a measured signal that can be used for external applications. STEVAL-MKI004V1 In addition to the MEMS sensor, the evaluation board utilizes an ST7-USB microcontroller which functions as a bridge between the sensor and the PC, on which it is possible to use the graphical user interface (GUI) included with the kit or dedicated software routines for customized applications.
