STMicroelectronics STEVAL-MKI062V1

Overview

STEVAL-MKI062V1 from STMicroelectronics is an iNEMO (INertial MOdule) demonstration board integrating a 10-DOF sensor suite: STM32F103RE ARM Cortex-M3 MCU, LPR530AL & LPY530AL dual-axis gyros (300°/s full scale), LIS331DLH 3-axis accelerometer (±2/4/8 g), HMC5843 3-axis magnetometer (±4 gauss), LPS001DL barometric pressure sensor (300–1100 mbar), and STLM75 temperature sensor (–55 to +125 °C), all interfaced via SPI/I²C/USB for inertial navigation prototyping.

For engineers reviewing the STEVAL-MKI062V1 datasheet, STEVAL-MKI062V1 pinout, STEVAL-MKI062V1 application, or STEVAL-MKI062V1 equivalent, this evaluation platform supports rapid development of motion-sensing systems requiring synchronized multi-sensor fusion, real-time environmental monitoring, and ZigBee® wireless telemetry in compact embedded form factors.

Technical Context

The board implements a tightly coupled sensor fusion architecture: the STM32F103RE MCU executes firmware to acquire analog gyro outputs (LPR530AL/LPY530AL), digitize accelerometer/magnetometer/pressure/temperature data via dedicated I²C/SPI peripherals, and manage time-synchronized sampling across all six inertial axes plus environmental channels. Onboard LBO monitoring and dual power inputs (USB + external connector) ensure stable operation during field testing.

Hardware-level signal conditioning includes configurable low-pass filters on gyro analog outputs (146 Hz cutoff), dedicated AVCC domains for analog sensor rails, isolated ground planes under the HMC5843 magnetometer per layout guidelines, and boot configuration jumpers (BOOT0/BOOT1) enabling Flash/SRAM/system memory startup modes - critical for firmware validation and recovery workflows.

Manufacturer

STMicroelectronics is a global semiconductor leader headquartered in Geneva, Switzerland, designing and manufacturing microcontrollers, sensors, power ICs, and automotive-grade components with focus on energy efficiency and system integration.

The iNEMO platform - including STEVAL-MKI062V1 - was developed by ST to accelerate adoption of high-accuracy inertial measurement units (IMUs) in consumer, industrial, and robotics applications through open-hardware reference designs and comprehensive firmware libraries.

FAQ

Does STEVAL-MKI062V1 support real-time sensor fusion out of the box?

Yes - the board ships with preloaded firmware and a PC-based GUI that displays synchronized time-series data from all 10 degrees of freedom. ST provides a complete firmware library (including sensor drivers and calibration routines) to enable custom fusion algorithms on the STM32F103RE, with no additional hardware required for basic operation.

What communication interfaces are exposed for host connection?

The board offers three primary host interfaces: USB 2.0 Full Speed (CDC virtual COM port), RS-232 via COM connector with RTS/CTS handshaking, and ZigBee® wireless via the SN260-compatible plug-in module. All interfaces share the same sensor data stream and support identical command protocols defined in ST's iNEMO documentation.

Is the HMC5843 magnetometer layout compliant with magnetic interference requirements?

Yes - the PCB layout strictly follows HMC5843 layout rules: no ground or power planes beneath the magnetometer footprint on either layer, dedicated clearance zone, and placement near board edge. The schematic also includes recommended decoupling (C43/C44) and orientation markings to minimize hard-iron distortion during calibration.

Can the gyroscope analog outputs be used directly without MCU digitization?

Yes - LPR530AL and LPY530AL provide buffered analog voltage outputs (0.5–4.5 V range) for roll/pitch/yaw axes, accessible at test points (GyroX_PR_OUT, GyroX_PY_OUT, etc.) and routed to MCU ADC inputs. External oscilloscopes or DAQ systems can monitor raw analog signals independently of the STM32 firmware stack.
