Smart digital output evaluation board based on nano accelerometer

STEVAL-MKI022V1 MEMS 3-Axis ±2g /±4g /±8g smart digital output evaluation board based on nano accelerometer LIS331DLH Features and Description Powered directly from USB connector I2C/SPI digital output interface Sleep to wake-up function 6D orientation detection The installation of the graphical user interface (GUI) for the STEVAL-MKI022V1 requires two steps: 1. installation of the software downloaded from www.st.com/mems 2. installation of the virtual COM driver needed to use the demonstration kit Both the hardware and software that compose the STEVAL-MKI022V1 demonstration kit have been designed to operate with Microsoft® Windows XP The STEVAL-MKI022V1 is a demonstration kit designed to provide the user with a complete, ready-to-use platform for demonstration of the LIS331DLH. The LIS331DLH is 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. In addition to the MEMS sensor, the demonstration 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 downloadable to the website or dedicated software routines for customized applications.
