Product details
Overview
STEVAL-MKI120V1 from STMicroelectronics is an adapter board for the LPS331AP MEMS pressure sensor, enabling direct plug-in evaluation via a standard DIL-24 socket. It provides full pinout access, on-board decoupling (100 nF + 10 µF), and seamless interoperability with the STEVAL-MKI109V2 motherboard for PC-based sensor characterization using Unico GUI.
For engineers reviewing the STEVAL-MKI120V1 datasheet, STEVAL-MKI120V1 pinout, STEVAL-MKI120V1 application, or STEVAL-MKI120V1 equivalent, this board delivers rapid prototyping capability for barometric pressure sensing in embedded environmental monitoring, altitude tracking, and industrial IoT edge nodes requiring validated sensor interface hardware.
Technical Context
The board implements a passive, unpowered signal translation interface between the LPS331AP's 16-pin LGA package and a 24-pin DIL socket, preserving all I²C (SCL/SDA), SPI (CS/SDO), interrupt (INT1/INT2), and power (Vdd_IO/Vdd) signals. No level-shifting or active logic is integrated - functionality relies entirely on mechanical pin mapping and passive decoupling.
It is designed exclusively for use with the STEVAL-MKI109V2 motherboard, which supplies regulated Vdd (2.5–3.3 V), hosts the STM32F303VC microcontroller, and handles USB-to-sensor protocol bridging. The adapter contains no firmware, MCU, or programmable elements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Form Factor | DIL-24 socket adapter board - enables direct insertion into standard 24-pin dual-in-line test sockets or carrier boards. |
| Sensor Interface | Full LPS331AP pinout support including I²C, SPI, two interrupt outputs, and dual power rails (Vdd/Vdd_IO). |
| Power Decoupling | Integrated 100 nF ceramic + 10 µF tantalum capacitors on VDD line - ensures stable supply for LPS331AP during dynamic pressure sampling. |
| Mechanical Compatibility | Fully compatible with STEVAL-MKI109V2 motherboard - mates via 2×12 header alignment and shares identical pin mapping convention. |
| Compliance | RoHS-compliant construction - meets EU Directive 2011/65/EU for hazardous substance restrictions. |

FAQ
Does STEVAL-MKI120V1 include the LPS331AP sensor?
No. The board is a passive adapter only - it does not contain the LPS331AP IC. Users must source and mount the LPS331AP separately onto the board's footprint before use. The board provides the socket interface and decoupling but no active silicon.
Can STEVAL-MKI120V1 operate standalone without STEVAL-MKI109V2?
No. It lacks power regulation, microcontroller, USB interface, or firmware. Operation requires connection to the STEVAL-MKI109V2 motherboard, which supplies power, executes sensor communication protocols, and relays data to a host PC via USB.
What software tools support STEVAL-MKI120V1?
ST's Unico GUI - a free Windows application - directly supports this adapter when used with STEVAL-MKI109V2. It enables real-time pressure/temperature readout, register configuration, and data logging without custom code development.
Are there alternative adapters for LPS331AP evaluation?
ST does not list any other official DIL-24 socket adapters for the LPS331AP. The STEVAL-MKI120V1 is the sole ST-recommended solution for socket-based evaluation of this sensor in conjunction with the MKI109V2 platform.
