Product details
Overview
STEVAL-MKI224V1 from STMicroelectronics is an adapter evaluation board for the LPS22DF ultra-low-power, high-precision MEMS barometric pressure sensor (260–1260 hPa absolute range, digital I²C/SPI output). It provides full LPS22DF pinout on a standard DIL24 socket and integrates VDD decoupling (100 nF + 10 µF) for immediate prototyping in embedded environmental sensing applications.
For engineers reviewing the STEVAL-MKI224V1 datasheet, STEVAL-MKI224V1 pinout, STEVAL-MKI224V1 application, or STEVAL-MKI224V1 equivalent, this board enables rapid integration with the STEVAL-MKI109D host platform, supports MEMS Studio GUI operation, and delivers verified signal routing for SCL, SDA, CS, INT1, SDO, and VDD_IO/VDD/GND interfaces.
Technical Context
The STEVAL-MKI224V1 is a passive adapter-no active components or firmware-designed exclusively to route LPS22DF signals (I²C and SPI modes) to a DIL24 footprint. It maps all 10 functional pins of the LPS22DF (including dual interrupt INT1, selectable CS, and separate VDD_IO/VDD supplies) without level-shifting or signal conditioning.
It requires connection to the STEVAL-MKI109D evaluation platform, which hosts a 32-bit microcontroller acting as a USB-to-sensor bridge. The adapter's fixed layout supports both default I²C (SDA/SCL) and configurable SPI (CS/SDO) communication protocols per LPS22DF specification.

FAQ
Does STEVAL-MKI224V1 include an onboard microcontroller or firmware?
No. The STEVAL-MKI224V1 is a passive adapter board with no MCU, memory, or embedded code. It routes LPS22DF signals only and requires the STEVAL-MKI109D platform for host-side processing, USB communication, and MEMS Studio interface functionality.
What communication protocols does STEVAL-MKI224V1 support for the LPS22DF?
It supports both I²C (via SCL/SDA pins) and SPI (via CS/SDO pins) as implemented by the LPS22DF sensor. Protocol selection is handled by the host platform (e.g., STEVAL-MKI109D) and external pull-up/pull-down configuration-not by the adapter itself.
Can STEVAL-MKI224V1 be used without the STEVAL-MKI109D platform?
Yes, but only with custom hardware that matches its DIL24 pinout and provides correct voltage levels (1.7–3.6 V for VDD, 1.7–3.6 V for VDD_IO), logic-level compatibility, and proper I²C/SPI bus termination. No onboard voltage translation or protocol handling is provided.
Is the LPS22DF sensor soldered onto STEVAL-MKI224V1?
Yes. The LPS22DF is permanently mounted on the board in its original QFN-10 package (2 mm × 2 mm × 1 mm). The adapter exposes all 10 terminals-including dedicated VDD_IO and VDD supplies-through the DIL24 footprint for direct access.
