STMicroelectronics STEVAL-MKI119V1

Overview

STEVAL-MKI119V1 from STMicroelectronics is a MEMS sensor demonstration kit featuring a 9-axis inertial measurement unit (IMU) with integrated accelerometer, gyroscope, and magnetometer, running iNEMOENgine_PW8 motion-fusion firmware delivering quaternion, heading/pitch/roll, linear acceleration, and gravity outputs via USB HID interface on Windows 8.

For engineers reviewing the STEVAL-MKI119V1 datasheet, STEVAL-MKI119V1 pinout, STEVAL-MKI119V1 application, or STEVAL-MKI119V1 equivalent, this board enables rapid evaluation of sensor fusion algorithms, USB HID-based motion sensing integration, calibration workflows (free/fixed movement), and DFU-based firmware updates for embedded motion-sensing development.

Technical Context

The STEVAL-MKI119V1 implements a complete sensor evaluation platform centered on an STM32 microcontroller hosting the iNEMOENgine_PW8 firmware, which performs real-time 9-axis sensor fusion using adaptive Kalman filtering across all three sensor types.

It operates as a USB HID-compliant sensor cluster device, exposing calibrated motion data-including quaternions, Euler angles, linear acceleration, and gravity vectors-without requiring host-side driver installation beyond standard Windows HID class support.

FAQ

What operating systems support the STEVAL-MKI119V1 out of the box?

Only Windows 8 is officially supported per UM1486. The board enumerates as a standard HID sensor device, leveraging native Windows HID class drivers. No Linux or macOS HID sensor class support is documented, and Windows 10/11 compatibility is not verified in the release notes.

How is firmware updated on the STEVAL-MKI119V1?

Firmware is updated via USB DFU mode: press Button 1 while connecting to PC, install ST's DfuSe v3.0 driver, then use DfuSe Demo to load the .dfu file from the Firmware directory. The process validates VID/PID, target memory address, and post-flash checksum verification.

Does the board include on-board calibration sensors or require external references?

No external reference is needed. Calibration is self-contained: pressing Button 3 initiates onboard routines that use internal sensor dynamics-free-space or fixed-axis motion-to compute bias, scale factor, and misalignment corrections for all nine axes without auxiliary equipment.

Can the iNEMOENgine_PW8 firmware be modified or extended?

The firmware binary is provided as a closed .dfu image; source code for the iNEMOENgine library is not included in UM1486. Developers may integrate the output data stream into host applications but cannot recompile or alter the sensor fusion logic on the STM32 without proprietary access to ST's engine source or SDK.
