STMicroelectronics STEVAL-MKI192V1

Overview

STEVAL-MKI192V1 from STMicroelectronics is a DIL24-socket-compatible adapter board for the LPS22HH high-accuracy MEMS barometric pressure sensor (260–1260 hPa, 0.008 hPa RMS noise, I²C/SPI digital interface). It provides full pin access, on-board decoupling (100 nF + 10 µF on VDD_IO), and direct plug-in capability into STEVAL-MKI109V3 and STEVAL-MKI109D evaluation motherboards for rapid sensor prototyping in environmental monitoring and altitude tracking systems.

For engineers reviewing the STEVAL-MKI192V1 datasheet, STEVAL-MKI192V1 pinout, STEVAL-MKI192V1 application, or STEVAL-MKI192V1 equivalent, this adapter enables immediate integration with STM32F401VE-based MEMS evaluation platforms and supports MEMS Studio GUI-driven configuration, real-time data streaming, and custom firmware development without soldering or breakout wiring.

Technical Context

The board implements a passive, unpowered signal translation interface between the LPS22HH's 10-pin DFN package and a standard 24-pin dual-in-line socket, preserving all functional pins (SCL, SDA, CS, SDO, INT1, VDD, VDD_IO, GND) with dedicated power rail decoupling. No level-shifting or active logic is integrated - it serves strictly as a mechanical and electrical breakout.

Designed exclusively for use with ST's MEMS evaluation ecosystem, it relies on host platforms (e.g., STEVAL-MKI109V3) for MCU-controlled sensor initialization, register access, and data acquisition. The board itself contains no microcontroller, memory, or firmware.

FAQ

Does STEVAL-MKI192V1 include an onboard microcontroller?

No. STEVAL-MKI192V1 is a passive adapter board only. It contains no MCU, memory, or firmware. Sensor communication and data processing must be handled by an external host platform such as STEVAL-MKI109V3 or STEVAL-MKI109D, which integrate the STM32F401VE microcontroller and USB-to-MCU bridge functionality.

Can STEVAL-MKI192V1 be used standalone without an evaluation motherboard?

No. The board lacks power regulation, USB interface, or host processor. It requires connection to a compatible ST evaluation platform (e.g., STEVAL-MKI109V3) to provide power, clock, I/O signaling, and PC communication. No standalone operation is supported.

What software tools support STEVAL-MKI192V1?

STEVAL-MKI192V1 is fully supported by ST's MEMS Studio graphical user interface, which runs on Windows and enables real-time sensor configuration, register read/write, data logging, and FFT analysis. It also works with ST's X-CUBE-MEMS1 firmware library for custom STM32-based applications.

Is the LPS22HH sensor pre-soldered on STEVAL-MKI192V1?

Yes. The LPS22HH in its 10-pin DFN package is factory-mounted and electrically tested on the board. All critical signals are routed with controlled impedance and proper grounding, and decoupling capacitors are pre-installed on the VDD_IO rail.
