Product details

Overview

STEVAL-MKI223V1K from STMicroelectronics is a demonstration board for the ILPS28QSW dual-range absolute digital barometric pressure sensor with integrated Qvar electrostatic sensing capability, featuring 1260 hPa and 4060 hPa full-scale ranges, water-resistant packaging, and I²C interface - used for swipe gesture detection and gas metering evaluation.

For engineers reviewing the STEVAL-MKI223V1K datasheet, STEVAL-MKI223V1K pinout, STEVAL-MKI223V1K application, or STEVAL-MKI223V1K equivalent, this kit enables rapid prototyping of Qvar-enabled human-machine interfaces and high-accuracy pressure sensing systems using the STEVAL-MKI109D host platform and MEMS Studio GUI.

Technical Context

The board implements the ILPS28QSW in a ready-to-use configuration with on-board decoupling (2.2 µF, 100 nF, 2.2 nF, 10 nF), ESD protection (ESDAXLC6-1BT2), and standard DIL24 socket-compatible pinout. It supports stacking with three electrode boards (STEVAL-MKE001A/002A/003A) to configure Qvar sensing geometry.

Designed exclusively for use with the STEVAL-MKI109D evaluation platform, it leverages its 32-bit microcontroller bridge to provide real-time sensor data streaming over USB to PC-based MEMS Studio or custom firmware - no additional hardware setup required.

FAQ

Does STEVAL-MKI223V1K operate standalone without additional hardware?

No. The board requires connection to the STEVAL-MKI109D evaluation platform to function - it lacks an onboard MCU or USB interface. The MKI109D provides the 32-bit microcontroller bridge, USB connectivity, and power regulation needed for sensor communication and PC interaction via MEMS Studio.

What electrode configurations are supported by the Qvar interface?

The board supports three distinct Qvar electrode topologies via stackable daughterboards: STEVAL-MKE001A (dual parallel electrodes), STEVAL-MKE002A (dual orthogonal electrodes), and STEVAL-MKE003A (top-down + top-up differential pair), each exposing dedicated Q+ and Q− pins with 10 MΩ bias resistors.

Is the ILPS28QSW sensor on this board factory-calibrated?

Yes. The ILPS28QSW device mounted on STEVAL-MKI223V1K is fully calibrated at production - delivering compensated digital pressure output (24-bit) and Qvar signal (16-bit) over I²C without requiring user calibration before evaluation.

Can multiple STEVAL-MKI223V1K boards be used simultaneously with one STEVAL-MKI109D?

No. The STEVAL-MKI109D platform supports only one sensor board per I²C bus segment. While the I²C address of ILPS28QSW is fixed (0x5D), simultaneous operation would require hardware modification (e.g., level-shifting multiplexers) or firmware-level time-division access - not supported out-of-box.
