Product details
Overview
STEVAL-MKI142V1 from STMicroelectronics is an LPS25H MEMS pressure sensor adapter board designed for plug-in evaluation via standard DIL-24 socket, featuring full LPS25H pinout, integrated decoupling capacitors on VDD, and direct compatibility with STEVAL-MKI109V2 motherboard for PC-based sensor characterization using Unico GUI.
For engineers reviewing the STEVAL-MKI142V1 datasheet, STEVAL-MKI142V1 pinout, STEVAL-MKI142V1 application, or STEVAL-MKI142V1 equivalent, this adapter enables rapid prototyping of barometric pressure sensing in portable environmental monitoring, altitude tracking, and industrial condition-sensing systems without custom PCB design.
Technical Context
The board implements a passive breakout interface between the LPS25H 24-pin SO16 MEMS pressure sensor and a DIL-24 socket, preserving all signal paths including I²C (SCL/SDA), interrupt (INT), chip select (CS), and power (VDD/GND). No active logic or level-shifting circuitry is present.
It serves exclusively as a mechanical and electrical translation layer-mapping the LPS25H's surface-mount SO16 footprint to through-hole DIL-24 pin spacing-while providing mandatory 100 nF ceramic decoupling on VDD per ST's LPS25H layout guidelines.
Key Specifications

| Socket Type | Standard 24-pin DIL (dual in-line) through-hole socket compatible with breadboard and test fixtures |
| Power Supply | Single 2.2–3.6 V supply; includes 100 nF ceramic decoupling capacitor on VDD line |
| Communication Protocol | Hardware-mapped I²C (SCL/SDA) and SPI (CS/SCL/SDA) pins exposed; no protocol conversion |
| Compatibility | Fully interoperable with STEVAL-MKI109V2 motherboard for USB-to-sensor bridge functionality |
| Compliance | RoHS-compliant PCB assembly with lead-free finish |

FAQ
Does STEVAL-MKI142V1 include the LPS25H sensor?
No. The board is a passive adapter only-it provides the socket and routing for mounting a separate LPS25H SO16 package. The LPS25H must be sourced and soldered separately or inserted into the DIL-24 socket if using a pre-mounted module variant.
What motherboard is required to communicate with a PC?
The STEVAL-MKI109V2 motherboard is required. It hosts a 32-bit STM32 microcontroller that acts as a USB-to-I²C/SPI bridge, enabling communication with ST's Unico GUI software or custom host applications on Windows, Linux, or macOS.
Can STEVAL-MKI142V1 operate standalone without a motherboard?
No. It has no onboard microcontroller, voltage regulator, or USB interface. It functions solely as a breakout-power, communication, and interrupt signals must be supplied externally via the DIL-24 socket or connected motherboard.
Is firmware or GUI software included with the board?
Unico GUI software is not bundled physically but is freely downloadable from ST's official website. It supports real-time pressure/temperature streaming, register configuration, and data logging for LPS25H when used with STEVAL-MKI109V2.
