Product details
Overview
STEVAL-MKI181V1 from STMicroelectronics is an adapter board for the LIS2MDL 3-axis magnetometer, designed to plug into a standard DIL24 socket and provide full pin access including SCL, SDA, CS, DRDY, VDD, and VDD_IO. It integrates decoupling capacitors (100 nF and 10 µF) and supports direct evaluation with STEVAL-MKI109V3/MIK109D development platforms. Used in rapid prototyping of compassing, tilt-compensated e-compass, and industrial position-sensing systems.
For engineers reviewing the STEVAL-MKI181V1 datasheet, STEVAL-MKI181V1 pinout, STEVAL-MKI181V1 application, or STEVAL-MKI181V1 equivalent, this board enables immediate LIS2MDL integration via DIL24 interface, compatibility with ST's MEMS Studio GUI, and seamless bridging to PC through supported 32-bit MCU-based platforms.
Technical Context
The board implements a passive breakout architecture with no active logic or level-shifting circuitry - all signals are routed directly from LIS2MDL pins to header terminals. Power conditioning includes dual-stage decoupling: 10 µF bulk capacitance and 100 nF high-frequency bypass on VDD, plus 220 nF on VDD_IO.
It provides mechanical and electrical compatibility with STEVAL-MKI109V3 and STEVAL-MKI109D via standardized 12-pin headers (JP1, JP2), enabling I²C communication (SCL/SDA), chip select (CS), interrupt/drdy signaling (DRDY), and dual-supply domain support (VDD and VDD_IO).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| DIL Socket Type | Standard 24-pin dual-in-line socket - enables plug-and-play LIS2MDL evaluation without soldering or custom PCB. |
| Supported Sensor | LIS2MDL 3-axis magnetometer - full pin mapping including I²C, CS, DRDY, and dual power rails (VDD/VDD_IO). |
| Decoupling Capacitors | 10 µF (bulk) + 100 nF (HF) on VDD; 220 nF on VDD_IO - ensures stable power delivery per LIS2MDL supply requirements. |
| Header Compatibility | Two 12-pin male headers (JP1, JP2) - matches mechanical and signal layout of STEVAL-MKI109V3/D platforms. |
| RoHS Compliance | Full RoHS 2011/65/EU compliance - meets environmental and regulatory requirements for commercial and industrial deployment. |

Manufacturer
STMicroelectronics is a global semiconductor leader headquartered in Geneva, designing and manufacturing microcontrollers, sensors, power ICs, and analog/mixed-signal devices for industrial, automotive, and consumer applications.
This board belongs to ST's STEVAL (ST Evaluation) platform family, engineered specifically to accelerate sensor evaluation and system-level integration using standardized interfaces and software-ready hardware.
FAQ
Does STEVAL-MKI181V1 include the LIS2MDL sensor?
No. The board is an adapter only and does not include the LIS2MDL IC. Users must supply the LIS2MDL in a compatible DIL24 socket or mount it separately. The board provides full pin access and required decoupling for immediate operation once the sensor is installed.
Which development platforms is STEVAL-MKI181V1 compatible with?
It is fully compatible with STEVAL-MKI109V3 and STEVAL-MKI109D - both feature a 32-bit STM32 MCU acting as a USB-to-sensor bridge. These platforms enable real-time data streaming to PC via MEMS Studio or custom firmware, with no additional interface hardware required.
What voltage domains does STEVAL-MKI181V1 support?
The board routes both VDD (core supply, 1.71–3.6 V) and VDD_IO (I/O supply, 1.71–3.6 V) independently, matching LIS2MDL's dual-rail architecture. Decoupling is applied separately: 10 µF + 100 nF on VDD, and 220 nF on VDD_IO.
Can STEVAL-MKI181V1 be used without STEVAL-MKI109V3/D?
Yes - it can interface with any host system providing I²C signals, proper voltage levels, and DRDY/CS control. However, ST-provided software (MEMS Studio), drivers, and example code assume use with MKI109-series platforms for plug-and-play functionality.
