STMicroelectronics STEVAL-MKI213V1

Overview

STEVAL-MKI213V1 from STMicroelectronics is an adapter board for the LPS27HHW MEMS barometric pressure sensor, designed to plug directly into a standard DIL24 socket and interface with the STEVAL-MKI109D evaluation platform. It provides full pin access-including SDO, SCL, SDA, CS, INT1, VDD, VDD_IO, and GND-with integrated 100 nF and 10 µF decoupling capacitors on the VDD line.

For engineers reviewing the STEVAL-MKI213V1 datasheet, STEVAL-MKI213V1 pinout, STEVAL-MKI213V1 application, or STEVAL-MKI213V1 equivalent, this board enables rapid prototyping of digital barometric sensing in industrial environmental monitoring, portable weather stations, and altitude-tracking wearables using I²C/SPI communication and interrupt-driven data acquisition.

Technical Context

The STEVAL-MKI213V1 implements a passive breakout architecture with no active signal conditioning or level-shifting circuitry-VDD_IO is independently routed to support flexible I/O voltage selection (1.71–3.6 V), while VDD powers the LPS27HHW core (1.7–3.6 V). All sensor signals are brought out unbuffered to dual-row 12-pin headers (JP1/JP2), preserving native timing and electrical characteristics for accurate characterization.

It relies entirely on the host platform (e.g., STEVAL-MKI109D) for MCU-based SPI/I²C protocol handling, interrupt management, and USB-to-PC data streaming. No onboard firmware, clock source, or power regulation is included-the board functions strictly as a mechanical and electrical interface extension of the LPS27HHW in a DIL24-compatible footprint.

FAQ

Does STEVAL-MKI213V1 include firmware or require programming?

No. The board contains no microcontroller or flash memory-it is a passive adapter. Firmware execution, sensor initialization, and data readout must be handled externally, typically by the STEVAL-MKI109D platform running MEMS Studio or custom host code.

Can STEVAL-MKI213V1 operate standalone without STEVAL-MKI109D?

No. It lacks power regulation, USB interface, or processing capability. It requires connection to a compatible host platform (e.g., STEVAL-MKI109D) or custom system providing regulated VDD/VDD_IO, I²C/SPI master logic, and interrupt handling.

What is the purpose of the separate VDD_IO pin?

VDD_IO supplies power to the LPS27HHW's digital I/O buffers independently from its core analog supply (VDD), enabling interoperability with host systems operating at 1.8 V or 3.3 V logic levels without level shifters.

Is the LPS27HHW sensor pre-soldered on STEVAL-MKI213V1?

Yes. The LPS27HHW is factory-mounted in a 10-pin HLGA package and electrically connected to the board's DIL24 breakout. No user assembly or rework is required-board is ready for immediate socket insertion and testing.
