Product details
Overview
STEVAL-MKI225A from STMicroelectronics is a DIL24-socket-compatible adapter board for the LPS28DFW absolute digital barometric pressure sensor, supporting dual full-scale ranges (1260 hPa and 4060 hPa), I²C interface (SCL/SDA), interrupt output (INT), and selectable slave address (SDO/SA0) - used in water metering and environmental sensing prototyping.
For engineers reviewing the STEVAL-MKI225A datasheet, STEVAL-MKI225A pinout, STEVAL-MKI225A application, or STEVAL-MKI225A equivalent, this board enables rapid integration with the STEVAL-MKI109D host platform or X-NUCLEO-IKS4A1 expansion board using MEMS Studio GUI or custom firmware.
Technical Context
The STEVAL-MKI225A provides direct breakout of all LPS28DFW signals-including VDD, GND, SCL, SDA, INT, and SDO/SA0-onto a 24-pin DIL footprint, enabling plug-and-play evaluation without soldering. It includes a 100 nF decoupling capacitor on the VDD line per sensor requirements.
It is designed exclusively as a mechanical and electrical interface adapter-not a standalone sensor-and requires connection to an external host MCU (e.g., STM32 via STEVAL-MKI109D) for power, clock, and data communication.
Key Specifications

FAQ
Does STEVAL-MKI225A include the LPS28DFW sensor?
Yes, the STEVAL-MKI225A board integrates the LPS28DFWTR pressure sensor in a water-resistant package. The sensor is pre-mounted and electrically connected with proper decoupling; no additional assembly is required for basic operation.
Which host platforms support STEVAL-MKI225A?
The board is fully compatible with the STEVAL-MKI109D evaluation platform (featuring a 32-bit STM32 MCU bridge) and the X-NUCLEO-IKS4A1 motion/environmental sensor expansion board. Both provide I²C connectivity, power, and firmware abstraction layers.
Can STEVAL-MKI225A operate standalone without a host MCU?
No. The board lacks onboard power regulation, clock generation, or firmware. It requires external power (1.7–3.6 V), I²C clock/data lines, and host-initiated commands - it functions only as a sensor interface adapter, not a self-contained module.
Is MEMS Studio software required to use STEVAL-MKI225A?
No, MEMS Studio is optional. While it provides GUI-based configuration and real-time data visualization, users may develop custom drivers and applications using standard I²C libraries targeting the LPS28DFW register map (e.g., pressure, temperature, interrupt control).
