STMicroelectronics STEVAL-IOD04KT1

Overview

STEVAL-IOD04KT1 from STMicroelectronics is a reference design kit for IO-Link v1.1 smart industrial sensors, integrating STM32G071EB (Arm® Cortex®-M0+ MCU, 64 MHz), L6364W dual-channel IO-Link transceiver, ISM330DHCX inertial module with FSM/ML core, and IIS2MDC 3-axis magnetometer. It operates from 7–32 V, features M8 industrial connector, and includes STLINK-V3MINI debugger and M8–M12 adapter.

For engineers reviewing the STEVAL-IOD04KT1 datasheet, STEVAL-IOD04KT1 pinout, STEVAL-IOD04KT1 application, or STEVAL-IOD04KT1 equivalent, this kit supports rapid prototyping of dual-channel IO-Link sensor nodes with embedded diagnostics, vibration/magnetic field monitoring, and firmware-upgradable MEMS control in factory automation environments.

Technical Context

The kit implements a complete IO-Link device node using L6364W's dual SIO/COM channels to drive two independent sensor data paths - one for inertial sensing (ISM330DHCX via I²C) and one for magnetic field measurement (IIS2MDC via I²C), both managed by the STM32G071EB running ST's certified IO-Link v1.1 stack and MEMS control firmware.

Power architecture centers on L6364W's integrated DC-DC converter delivering regulated 3.3 V to all logic ICs; surge protection (±3 A_PK, 500 Ω coupling) and reverse-polarity protection ensure robustness in harsh industrial wiring environments, while EMC/EMI compliance meets industrial standards.

FAQ

Does STEVAL-IOD04KT1 include production-ready firmware?

Yes - it ships preloaded with ST's certified IO-Link v1.1 demo stack and MEMS sensor control software (STSW-IOD04K), including an IODD file compliant with IO-Link specification v1.1. The firmware supports transparent, single-octet, and multioctet transmission modes and is field-upgradable via STLINK-V3MINI.

Can the main board STEVAL-IOD004V1 be purchased separately?

No - STEVAL-IOD004V1 is not offered as a standalone product. It is exclusively supplied as part of the STEVAL-IOD04KT1 evaluation kit and is not orderable individually through ST or authorized distributors.

What protections does the kit provide against industrial electrical stress?

The kit integrates L6364W-based surge protection rated to ±3 A_PK with 500 Ω coupling impedance and reverse-polarity protection on the 7–32 V input rail. All signal lines are ESD-hardened, and the PCB layout follows industrial EMC/EMI design rules verified per relevant IEC standards.

Is sensor expansion supported beyond the onboard ISM330DHCX and IIS2MDC?

Yes - a dedicated 10-pin expansion connector (J2) provides access to I²C bus (SCL/SDA), USART2 signals, DRDY outputs, and 3.3 V/GND. This allows connection of third-party or custom sensors while retaining synchronization with the IO-Link stack and MEMS control framework.
