STMicroelectronics STEVAL-MKI175V1

Overview

STEVAL-MKI175V1 from STMicroelectronics is a DIL24 socket-compatible adapter board for the LIS2DE12 3-axis digital accelerometer, providing full pin access, on-board decoupling (100 nF + 10 µF on VDD), and direct plug-in capability into the STEVAL-MKI109D evaluation platform for rapid prototyping in motion-sensing applications.

For engineers reviewing the STEVAL-MKI175V1 datasheet, STEVAL-MKI175V1 pinout, STEVAL-MKI175V1 application, or STEVAL-MKI175V1 equivalent, this board enables immediate sensor integration testing with MEMS Studio GUI support, I²C/SPI interface validation, interrupt-driven motion detection verification, and low-power wake-up behavior characterization in embedded inertial systems.

Technical Context

The board implements a passive signal translation interface between the LIS2DE12's 16-pin LGA package and a standard 24-pin DIL socket, preserving all functional pins including dual interrupt outputs (INT1/INT2), configurable I²C/SPI select (SDO/SA0), chip select (CS), and dual power domains (VDD and Vdd_IO). No active logic or level-shifting circuitry is integrated.

It is designed exclusively as a mechanical and electrical breakout-no firmware, microcontroller, or USB interface is included. Compatibility with STEVAL-MKI109D relies entirely on external host bridge functionality, and all sensor configuration and data acquisition must be performed via the connected evaluation platform.

FAQ

Does STEVAL-MKI175V1 include an onboard microcontroller or USB interface?

No. The board contains only passive components and routing traces. It has no embedded processor, firmware, or communication interface. All sensor control and data readout require connection to an external host platform such as the STEVAL-MKI109D, which provides the MCU bridge and PC connectivity.

Can STEVAL-MKI175V1 operate independently without STEVAL-MKI109D?

No. It lacks power regulation, clock generation, and host interface circuitry. While it can be powered externally via VDD/Vdd_IO pins, functional operation-including register access and interrupt handling-requires a compatible host platform to drive the LIS2DE12's digital interface and interpret its output.

What are the voltage requirements for VDD and Vdd_IO on STEVAL-MKI175V1?

VDD must be supplied at 1.71–3.6 V DC for LIS2DE12 core operation; Vdd_IO accepts 1.71–3.6 V for I/O level compatibility. Both rails are decoupled independently, and the board does not include voltage translation-host interface logic levels must match the selected rail.

Is the LIS2DE12 pre-soldered on STEVAL-MKI175V1?

Yes. The LIS2DE12 is factory-mounted in its native 16-pin LGA package and electrically connected to all DIL24 socket pins per the official pin mapping in DB3059. No user assembly or rework is required to begin evaluation.
