Product details

Overview

STEVAL-MKI227KA from STMicroelectronics is a ready-to-use evaluation kit for the LSM6DSV16X 6-axis IMU with integrated Qvar electrostatic sensing, featuring three configurable QVAR electrodes (swipe, finger, generic), full DIL24 pinout access, and jumper-based configuration for sensor mode selection - used in AR smart glasses development and AI-enhanced motion interface prototyping.

For engineers reviewing the STEVAL-MKI227KA datasheet, STEVAL-MKI227KA pinout, STEVAL-MKI227KA application, or STEVAL-MKI227KA equivalent, this board enables rapid validation of LSM6DSV16X's fused 3-axis accelerometer + 3-axis gyroscope output, Qvar electrode response, and I²C/SPI interface timing under real-world MEMS Studio GUI control.

Technical Context

The STEVAL-MKI227KA implements a hardware abstraction layer between the LSM6DSV16X and host systems via standardized DIL24 socket interface, supporting both direct connection to STEVAL-MKI109D (32-bit MCU bridge) and standalone use with external controllers. It integrates decoupling capacitors (2.2 µF + 100 nF on VDD, 110 pF on VDDIO) and ESD protection (ESDALCL5-1BM2) on all signal lines.

Qvar electrode routing includes three dedicated 3-pin SMD headers (QVAR1, QVAR2, QVAR3 variants across sub-boards STEVAL-MKE001A/002A/003A), each with 10 MΩ pull-up/down resistors and configurable top-down/top-up sensing paths - enabling swipe/finger/generic gesture detection without firmware modification.

FAQ

Does STEVAL-MKI227KA require external programming hardware to operate?

No. The board is preconfigured for immediate use with the LSM6DSV16X powered and biased correctly. When connected to STEVAL-MKI109D, it leverages the onboard 32-bit microcontroller as a USB-to-sensor bridge - no external programmer or debugger is needed for basic sensor readout or Qvar electrode testing via MEMS Studio.

Can STEVAL-MKI227KA be used without the STEVAL-MKI109D platform?

Yes. The DIL24 socket provides full access to all LSM6DSV16X pins (including I²C, SPI, INT1/INT2, and Qvar electrodes), allowing direct connection to custom host controllers. Power sequencing, decoupling, and ESD protection are already implemented on-board per ST's DB4862 design guidelines.

What is the role of the jumpers on STEVAL-MKI227KA?

The jumpers configure LSM6DSV16X operating modes: SA0/SCL/SDA pull-up/down selection for I²C address or SPI mode enablement, and Qvar electrode routing (swipe vs. finger vs. generic) by connecting specific resistor networks (R1–R8, 10 MΩ) to Q1/Q2 terminals per schematic Figures 1–4.

Which software tools support STEVAL-MKI227KA out of the box?

MEMS Studio (ST's official GUI) fully supports STEVAL-MKI227KA when paired with STEVAL-MKI109D, enabling real-time sensor data streaming, Qvar electrode calibration, register-level configuration, and export of fused orientation quaternions. ST also provides STM32Cube function packs (FP-SNS-ALLMEMS1) with validated drivers and example projects.
