STMicroelectronics STEVAL-MKIT01V2

Overview

STEVAL-MKIT01V2 from STMicroelectronics is a MEMS sensor sample kit comprising four plug-in adapter boards-STEVAL-MKI179V1 (LIS2DW12 3-axis accelerometer), STEVAL-MKI197V1 (LSM6DSOX 6-axis AI-enhanced IMU), STEVAL-MKI181V1 (LIS2MDL 3-axis magnetometer), and STEVAL-MIC004V1 (MP23ABS1 analog MEMS microphone)-all designed for DIL-24 socket compatibility and standalone I²C/analog evaluation.

For engineers reviewing the STEVAL-MKIT01V2 datasheet, STEVAL-MKIT01V2 pinout, STEVAL-MKIT01V2 application, or STEVAL-MKIT01V2 equivalent, this kit enables rapid comparative evaluation of ST's high-performance MEMS sensors across motion, orientation, magnetic field, and acoustic sensing domains without custom hardware or firmware development.

Technical Context

The kit integrates four independently functional sensor daughterboards, each pre-mounted on standardized DIL-24 footprints for mechanical and electrical interoperability with the STEVAL-MKI109V3 motherboard (STM32F401VET6-based) or direct connection via I²C and analog cables. No shared power or signal routing exists between boards-they operate as discrete, hot-pluggable modules.

All boards support standard 3.3 V supply and level-compatible I²C interfaces (except STEVAL-MIC004V1, which outputs analog voltage); the LSM6DSOX board includes embedded machine learning core (FSM) for on-sensor AI processing, while LIS2DW12 offers configurable low-power wake-up and tilt detection modes.

FAQ

Does STEVAL-MKIT01V2 include firmware or software?

No. The kit contains only hardware: four sensor adapter boards and mechanical interface documentation. Firmware must be loaded separately onto the STEVAL-MKI109V3 motherboard or host MCU using ST's Unico GUI, X-CUBE-MEMS1, or custom I²C drivers. No onboard memory or bootloader is present on any daughterboard.

Can STEVAL-MKIT01V2 boards be used without the STEVAL-MKI109V3 motherboard?

Yes. Each board supports standalone evaluation: LIS2DW12, LSM6DSOX, and LIS2MDL communicate over I²C using external pull-ups and 3.3 V supply; STEVAL-MIC004V1 provides analog output directly to an ADC input. No motherboard is required for basic functionality verification.

What is the role of the DIL-24 socket compatibility?

The DIL-24 footprint standardizes mechanical mounting and pin mapping across all four boards, enabling interchangeable placement on STEVAL-MKI109V3 or custom carrier boards. Pin assignments follow ST's documented DIL-24 sensor layout-no custom PCB layout needed for integration.

Is the MP23ABS1 microphone board compatible with other ST expansion boards?

Yes. STEVAL-MIC004V1 is specifically designed to plug into the X-NUCLEO-AMICAM1 audio expansion board, which provides bias voltage, amplification, and ADC interfacing. It is not electrically compatible with non-audio-focused ST expansion boards like X-NUCLEO-IKS01A3.
