STMicroelectronics STEVAL-MKI164V1

Overview

STEVAL-MKI164V1 from STMicroelectronics is an adapter board for the LIS2HH12 ultra-low-power 3-axis accelerometer, providing full pin access via a standard DIL24 socket. It integrates required VDD decoupling capacitors and enables direct plug-in evaluation with STEVAL-MKI109V2/V3 motherboards.

For engineers reviewing the STEVAL-MKI164V1 datasheet, STEVAL-MKI164V1 pinout, STEVAL-MKI164V1 application, or STEVAL-MKI164V1 equivalent, this board supports rapid MEMS inertial sensor prototyping, GUI-based characterization via Unico software, and integration into custom embedded motion-sensing systems.

Technical Context

The board implements a passive mechanical and electrical interface between the LIS2HH12 in its original LGA-12 package and a DIL24 footprint, preserving all signal, power, and ground connections without level-shifting or signal conditioning. It routes VDD, GND, SCL, SDA, INT1, INT2, and SA0 with 100 nF ceramic decoupling on VDD.

Designed exclusively for evaluation use, it contains no active components or firmware-only passive routing and filtering-and relies entirely on host motherboard (e.g., STEVAL-MKI109V2/V3) for MCU-controlled I²C communication, interrupt handling, and PC-side GUI interaction.

FAQ

Does STEVAL-MKI164V1 include a microcontroller or firmware?

No. The board is purely passive: it contains only copper traces, pads, and a single 100 nF decoupling capacitor. All processing, I²C communication, and GUI interaction are handled by the host motherboard (e.g., STEVAL-MKI109V2/V3) and PC software-no onboard MCU or flash memory is present.

Can STEVAL-MKI164V1 be used without STEVAL-MKI109V2/V3 motherboards?

Yes-but only with external circuitry providing I²C master capability, proper voltage regulation (2.2–3.6 V), and interrupt handling. The board lacks pull-up resistors, level shifters, or logic drivers; users must supply these externally if not using ST's supported motherboards.

What software tools support STEVAL-MKI164V1?

ST's Unico GUI (Windows-based) is fully compatible when used with STEVAL-MKI109V2/V3 motherboards. Users can also develop custom firmware using ST's X-CUBE-MEMS1 software package, which provides HAL drivers, sensor fusion examples, and raw data streaming APIs for LIS2HH12.

Is STEVAL-MKI164V1 RoHS compliant and suitable for production design?

Yes, it is RoHS compliant per the data brief. However, it is strictly an evaluation tool-not a production-ready module. Its DIL24 form factor and lack of environmental sealing or ESD hardening mean it is intended only for lab validation, not end-product integration.
