STMicroelectronics STEVAL-MKI211V1K

Overview

STEVAL-MKI211V1K from STMicroelectronics is a ready-to-use evaluation kit comprising the LIS25BA 3-axis digital accelerometer mounted on a dedicated PCB, connected via flat cable to the STEVAL-MKIGIBV3 DIL24 adapter board, and fully compatible with the STEVAL-MKI109D platform. It delivers low-noise, high-bandwidth motion sensing (±2g/±4g/±8g/±16g FS), TDM digital output interface, and supports vibration analysis in industrial equipment monitoring.

For engineers reviewing the STEVAL-MKI211V1K datasheet, STEVAL-MKI211V1K pinout, STEVAL-MKI211V1K application, or STEVAL-MKI211V1K equivalent, this kit enables rapid validation of LIS25BA sensor integration, TDM-based data streaming, MEMS Studio GUI interaction, and mechanical mounting options including double-sided adhesive or corner-hole fastening.

Technical Context

The STEVAL-MKI211V1K implements a fixed-hardware sensor interface: the LIS25BA is soldered centrally on the main board and communicates via TDM (BICK/WCLK/SDOUT/MCLK) and I²C (SCL/SDA) signals routed through a flat cable to the STEVAL-MKIGIBV3 adapter, which maps those signals to a standard DIL24 footprint for plug-in compatibility with STEVAL-MKI109D.

It includes on-board decoupling (100 nF + 1 µF on VDD), RoHS-compliant construction, and dual mounting methods - adhesive-backed for temporary equipment attachment or screw-mounted via four corner holes - enabling repeatable placement during vibration testing without mechanical coupling artifacts.

FAQ

Does STEVAL-MKI211V1K include the STEVAL-MKI109D platform?

No. The STEVAL-MKI211V1K is a sensor-specific daughterboard that requires the separate STEVAL-MKI109D main evaluation platform to operate. It connects via flat cable to the STEVAL-MKIGIBV3 adapter, which plugs into the DIL24 socket on the STEVAL-MKI109D board.

What software tools are supported for configuring and visualizing LIS25BA data?

The kit is fully supported by ST's MEMS Studio graphical user interface, downloadable free from st.com. MEMS Studio provides real-time TDM data streaming, register configuration, FFT analysis, and export of time-domain waveforms for vibration diagnostics.

Can the LIS25BA on this board be replaced with another sensor?

No. The LIS25BA is permanently soldered to the STEVAL-MKI211V1K PCB and not socketed. The board is designed exclusively for evaluating this specific sensor; replacement would require rework and void calibration integrity and mechanical alignment.

Is external power required, or does it draw power from the STEVAL-MKI109D?

It draws all operating power (VDD and VDDIO) directly from the STEVAL-MKI109D platform via the STEVAL-MKIGIBV3 adapter. No external power supply or batteries are needed - the board includes only passive decoupling capacitors (100 nF and 1 µF).
