STMicroelectronics LPR403AL Manuals

The LPR403AL is a low-power dual-axis MEMS motion sensor capable of measuring angular rate along pitch and roll axes. It provides excellent temperature stability and high resolution over an extended operating temperature range (-40 °C to +85 °C). The LPR403AL has a full scale of ±30 dps and is capable of detecting rates with a -3 dB bandwidth up to 140 Hz.

The STEVAL-MKI099V1 is an adapter board designed to facilitate the evaluation of MEMS devices in the LPR403AL product family. The board can be plugged into a standard DIL 24 socket and provides the complete LPR403AL pinout. The pinout of the adapter is fully compatible with all other available adapter boards, making it possible to easily switch from one sensor to another during device evaluation without the need for board redesign.

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.
