Product details
Overview
STEVAL-MKI022V1 from STMicroelectronics is a USB-powered MEMS demonstration board built around the LIS331DLH 3-axis digital accelerometer, supporting ±2g/±4g/±8g full-scale ranges, I²C/SPI interface, and 6D orientation detection for rapid evaluation of motion-sensing applications in industrial and consumer devices.
For engineers reviewing the STEVAL-MKI022V1 datasheet, STEVAL-MKI022V1 pinout, STEVAL-MKI022V1 application, or STEVAL-MKI022V1 equivalent, this kit delivers ready-to-run Windows XP-compatible GUI software, sleep-to-wake functionality, and direct PC connectivity via USB without external power supplies or drivers.
Technical Context
The board integrates the LIS331DLH MEMS sensor with an ST7-USB microcontroller acting as a USB-to-sensor bridge, enabling real-time data streaming and configuration via host PC. It implements embedded 6D orientation detection logic and configurable wake-up interrupt generation based on acceleration thresholds.
Hardware design supports both I²C and SPI communication modes through jumper-selectable interface routing, while onboard LEDs provide visual status feedback for power, communication activity, and motion-triggered events - all powered directly from USB 5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Sensor | LIS331DLH 3-axis linear accelerometer with digital output |
| Full-Scale Range | Selectable ±2g / ±4g / ±8g - determines dynamic range and resolution for motion capture |
| Interface Modes | I²C and SPI - dual protocol support enables flexible integration with diverse host controllers |
| Power Source | USB 5 V only - eliminates need for external power supply or voltage regulation circuitry |
| Orientation Detection | 6D (free-fall, tilt, portrait/landscape) - enables context-aware UI and power management decisions |
| GUI Compatibility | Microsoft Windows XP only - limits deployment to legacy industrial test environments |

FAQ
Does STEVAL-MKI022V1 support modern Windows versions like Windows 10 or 11?
No. The official GUI software and driver stack were validated exclusively for Microsoft Windows XP. No official updates or compatibility patches exist for newer Windows versions, and USB enumeration may fail without custom firmware or host-side adaptation.
Can the LIS331DLH sensor be replaced with another accelerometer on this board?
No. The LIS331DLH is soldered directly onto the PCB with no socket or footprint compatibility for alternative sensors. Its I²C/SPI pinout and voltage-level requirements are tightly coupled to the ST7-USB microcontroller's interface design.
Is STEVAL-MKI022V1 still in active production or recommended for new designs?
No. STMicroelectronics has marked STEVAL-MKI022V1 as obsolete, with no active manufacturing or technical support. It remains available for legacy system maintenance but is not recommended for new product development.
What firmware runs on the ST7-USB microcontroller?
The ST7-USB executes proprietary firmware that handles USB CDC communication, sensor register access, data streaming, and GPIO control for LEDs and interrupts. ST did not release source code or reprogrammable hex files for this board.
