STMicroelectronics STEVAL-MKI210V1K

Overview

STEVAL-MKI210V1K from STMicroelectronics is a ready-to-use evaluation board featuring the ISM330DHCX 3-axis accelerometer and 3-axis gyroscope, mounted at PCB center with precision alignment for vibration analysis. It includes double-sided adhesive mounts, corner mounting holes, and full ISM330DHCX pinout routed to a DIL-24 socket via STEVAL-MKIGIBV2 adapter. Compatible with STEVAL-MKI109V3 motherboard and Unico GUI software.

For engineers reviewing the STEVAL-MKI210V1K datasheet, STEVAL-MKI210V1K pinout, STEVAL-MKI210V1K application, or STEVAL-MKI210V1K equivalent, this board enables rapid prototyping of inertial measurement units in IoT edge devices, predictive maintenance systems, and motion-controlled industrial equipment - with verified sensor interface, power decoupling, and host bridge compatibility.

Technical Context

The board implements the ISM330DHCX iNEMO IMU - a MEMS-based inertial measurement unit with integrated machine learning core (MLC) and finite state machine (FSM). It supports I²C and SPI digital interfaces, operates from 1.71 V to 3.6 V supply, and delivers ±2/±4/±8/±16 g full-scale acceleration and ±125/±250/±500/±1000/±2000 dps angular rate sensing.

Signal conditioning includes on-board 1 µF and dual 100 nF decoupling capacitors on VDD/VDDIO lines, plus 33 Ω series resistors on SDA/SCL/INT1/INT2 lines for noise suppression and slew-rate control. The DIL-24 header provides direct access to all ISM330DHCX pins including CS, SDO, INT1, INT2, and MLC-triggered interrupt outputs.

FAQ

Does STEVAL-MKI210V1K include the ISM330DHCX sensor pre-soldered?

Yes. The ISM330DHCX is permanently soldered at the geometric center of the PCB to ensure mechanical symmetry and minimal mounting-induced bias. No user assembly or sensor replacement is supported - the board ships fully populated and calibrated per ST factory test procedures.

Can STEVAL-MKI210V1K operate standalone without STEVAL-MKI109V3?

No. The board lacks an onboard microcontroller or USB interface. It requires connection via flat cable to STEVAL-MKIGIBV2 (DIL-24 adapter), then to STEVAL-MKI109V3 motherboard, which hosts the STM32F401VE MCU and handles USB communication, sensor register access, and data streaming to PC software.

What software tools are supported for data acquisition?

ST's Unico GUI is the primary supported tool - it provides real-time sensor data visualization, MLC configuration, FSM setup, and register read/write. Custom applications can use ST's X-CUBE-MEMS1 middleware library with HAL drivers for STM32 MCUs, accessible via STM32CubeMX and STM32CubeIDE.

Are the INT1 and INT2 pins configurable for motion detection events?

Yes. Both INT1 and INT2 are hardware interrupt outputs from the ISM330DHCX, programmable via internal registers to signal free-fall, wake-up, 6D orientation, step detection, or MLC/FSM pattern recognition events - with push-pull or open-drain output modes selectable in configuration.
