STMicroelectronics STEVAL-MKI195V1

Overview

STEVAL-MKI195V1 from STMicroelectronics is a DIL24 socket-compatible adapter board for the LSM6DSRX 6-axis IMU, providing full pin access, on-board VDD decoupling capacitors, and RoHS/WEEE compliance. It enables rapid prototyping and sensor evaluation within custom host systems using ST's MEMS Studio GUI or custom firmware.

For engineers reviewing the STEVAL-MKI195V1 datasheet, STEVAL-MKI195V1 pinout, STEVAL-MKI195V1 application, or STEVAL-MKI195V1 equivalent, key considerations include DIL24 mechanical compatibility, LSM6DSRX signal routing fidelity, support for STM32F401VE-based evaluation platforms (STEVAL-MKI109V3/STEVAL-MKI109D), and integration readiness with MEMS Studio software.

Technical Context

The STEVAL-MKI195V1 is a passive breakout adapter - not an active evaluation board - with no embedded microcontroller or firmware. Its sole function is to electrically and mechanically interface the LSM6DSRX in a standard 24-pin dual-in-line footprint, preserving all I²C/SPI signals, interrupt outputs, and power domains.

It is designed exclusively for use with ST's professional MEMS evaluation ecosystem: it mates directly with the STEVAL-MKI109V3 and STEVAL-MKI109D motherboards, which provide the STM32F401VE host MCU, USB bridge, and MEMS Studio communication stack.

FAQ

Does the STEVAL-MKI195V1 include an onboard microcontroller?

No. The STEVAL-MKI195V1 is a passive adapter board with no embedded processor, memory, or firmware. It relies entirely on external host platforms like the STEVAL-MKI109V3 or STEVAL-MKI109D for MCU functionality, USB communication, and sensor data processing.

What software tools are supported for configuring the LSM6DSRX via this adapter?

ST MEMS Studio - a free, Windows-based graphical user interface - is fully supported when the STEVAL-MKI195V1 is used with STEVAL-MKI109V3 or STEVAL-MKI109D. Custom firmware using ST's X-CUBE-MEMS1 software package is also compatible.

Can the STEVAL-MKI195V1 be used standalone without an evaluation motherboard?

No. It lacks power regulation, USB interface, and host MCU logic. It must be inserted into a DIL24 socket on a compatible motherboard (e.g., STEVAL-MKI109V3) to provide power, clock, and bidirectional communication to the LSM6DSRX.

Is the LSM6DSRX machine learning core accessible through this adapter?

Yes. All LSM6DSRX features - including the embedded machine learning core (FSM and OIS), accelerometer, gyroscope, and interrupt outputs - are fully routed and electrically accessible via the STEVAL-MKI195V1's DIL24 pins when used with a supporting host platform.
