STMicroelectronics STEVAL-IFS001V1

Overview

STEVAL-IFS001V1 from STMicroelectronics is a 3-axis MEMS accelerometer demonstration kit built around the LIS3LV02DQ sensor and a µPSD microcontroller, supporting ±2g/±6g full-scale range selection, 256 Kbytes on-board data storage, and USB PC interface for real-time or stored-data analysis in motion-sensing applications.

For engineers reviewing the STEVAL-IFS001V1 datasheet, STEVAL-IFS001V1 pinout, STEVAL-IFS001V1 application, or STEVAL-IFS001V1 equivalent, this kit enables rapid validation of LIS3LV02DQ-based motion detection, vibration monitoring, and tilt-sensing systems with GUI-driven spectrum analysis and configurable acceleration ranges.

Technical Context

The kit integrates the LIS3LV02DQ 3-axis analog-output MEMS accelerometer with a ST uPSD3300-based control board featuring embedded Flash (256 KB), USB 2.0 interface, and configurable I²C/SPI communication to the sensor. Power is supplied via USB (5 V) with local 3.3 V and 2.4 V regulation.

Sensor configuration is managed through hardware jumpers and firmware, enabling full-scale range switching between ±2g and ±6g; output data is accessible either live via USB streaming or post-capture from µPSD memory, with GUI support for time-domain and frequency-domain visualization.

FAQ

What is the primary sensor used on the STEVAL-IFS001V1 board?

The board uses the LIS3LV02DQ - a low-voltage, low-power 3-axis analog-output MEMS accelerometer with user-selectable ±2g or ±6g full-scale range. It interfaces directly with the uPSD microcontroller via configurable I²C/SPI lines and provides raw analog outputs for each axis, which are digitized onboard.

Does the STEVAL-IFS001V1 require external power or drivers?

No external power supply is needed: the board draws 5 V power directly from the USB port. No proprietary drivers are required - it enumerates as a standard USB CDC device, and the included Windows GUI software communicates using native USB HID protocols without additional installation steps.

Can acceleration data be logged without a PC connected?

Yes - the integrated ST uPSD3300 microcontroller includes 256 Kbytes of on-chip Flash memory, allowing autonomous data acquisition and storage of acceleration samples. Data can later be retrieved via USB once the PC is reconnected, enabling field-deployable logging in portable or remote environments.

Is the GUI software compatible with modern Windows versions?

The original GUI was released in 2007 for Windows XP but remains functional on Windows 10 and 11 in compatibility mode. Source code for the µPSD firmware and host application is provided in the official ST archive, permitting recompilation and adaptation for current OS requirements and extended functionality.
