STMicroelectronics STEVAL-IDP003V1

Overview

STEVAL-IDP003V1 from STMicroelectronics is an IO-Link industrial modular sensor evaluation kit comprising a main board with L6362A IO-Link transceiver and STM32L071CZ Arm Cortex-M0+ microcontroller, supporting 400 kHz I²C communication, 32 V max supply, integrated DC-DC converter and linear regulator, and reverse polarity protection. It hosts four interchangeable sensor daughter boards (temperature, vibration, accelerometer, proximity) and connects via M12 industrial connector to IO-Link masters over 20 m cable.

For engineers reviewing the STEVAL-IDP003V1 datasheet, STEVAL-IDP003V1 pinout, STEVAL-IDP003V1 application, or STEVAL-IDP003V1 equivalent, key selection considerations include IO-Link PHY compliance (IEC 61131-9), multi-sensor interoperability via standardized I²C interfaces, industrial EMC robustness per IEC61000-4-2/4 and EN60947, and support for condition monitoring and predictive maintenance prototyping.

Technical Context

The kit implements a complete IO-Link device node architecture: L6362A handles physical layer signaling (3-wire interface: L+, L−, IO-Link data), diagnostics, and reverse polarity protection, while the STM32L071CZ executes sensor fusion, data preprocessing, and IO-Link parameterization (process data, vendor-specific data, identification). All sensors communicate exclusively over dedicated 400 kHz I²C buses with isolated power domains (3v3_T, 3v3_Ax, 3v3_PRX).

PCB layout adheres to industrial mechanical constraints (8 mm × 70 mm sensor footprint, 0.8 mm thickness) and electromagnetic compatibility requirements-EN60947 for industrial control equipment and IEC61000-4-2 (ESD ±8 kV contact) / IEC61000-4-4 (EFT ±2 kV) immunity-enabling direct integration into factory automation test benches.

FAQ

What sensors are included with the STEVAL-IDP003V1 kit?

The kit ships with five boards: main board STEVAL-IDP003V1 and four daughter boards - STEVAL-IDP003V1T (STTS751 temperature sensor), STEVAL-IDP003V1V (IIS2DH vibration sensor), STEVAL-IDP003V1A (IIS328DQ accelerometer), and STEVAL-IDP003V1P (VL6180X proximity sensor). All connect via standardized 10-pin headers and operate on isolated 3.3 V rails.

Does the STEVAL-IDP003V1 support IO-Link master connection out of the box?

Yes - it features an industrial M12 connector wired for standard IO-Link 3-wire topology (L+, L−, data) and is fully compliant with IEC 61131-9. No additional level-shifting or adapter hardware is required to connect to commercial IO-Link masters, including those from Pepperl+Fuchs, Balluff, or ifm.

Can the STM32L071CZ firmware be reprogrammed or debugged?

Yes - the board provides SWD (SWDIO/SWCLK) and NRST pins accessible via header J2, enabling full debugging and firmware updates using ST-LINK/V2 or compatible debug probes. The STM32L071CZ is preloaded with IO-Link device stack firmware but supports custom application development via STM32CubeIDE and HAL libraries.

Is the STEVAL-IDP003V1 RoHS compliant and suitable for industrial deployment?

Yes - the board is RoHS compliant and designed to meet IEC61000-4-2/4 (ESD/EFT immunity) and EN60947 (industrial control equipment) standards. Its PCB layout, component selection, and enclosure-ready mechanical dimensions make it suitable for lab validation and pilot-line integration in industrial settings.
