This document is a data brief for STMicroelectronics' STEVAL-MKI081V1 MEMS demonstration board. The board is based on LPR403AL (analog output 2-axis gyroscope) and features analog and digital working modes. It includes a sensing element and an IC interface capable of translating information from the sensing element into a measured signal for external applications. The board also uses an ST7 microcontroller as a bridge between the sensor and the PC. Users can download the graphical user interface (GUI) from the website or use dedicated software routines for customized applications. The demonstration board can be used in analog mode, where the microcontroller is disabled and the analog outputs are available to the user, or in digital mode, where the microcontroller is enabled and allows digital acquisition of the device's output signals for viewing on a PC.
