Product details
Overview
STEVAL-MKI208V1K from STMicroelectronics is an evaluation kit comprising the IIS3DWB ultrawide-bandwidth (2.4 kHz) low-noise 3-axis digital vibration sensor mounted on a DIL24-compatible adapter board, with integrated decoupling capacitors, double-sided adhesive mounting aids, and mechanical mounting holes - designed for rapid integration into condition monitoring and predictive maintenance test setups.
For engineers reviewing the STEVAL-MKI208V1K datasheet, STEVAL-MKI208V1K pinout, STEVAL-MKI208V1K application, or STEVAL-MKI208V1K equivalent, key selection considerations include IIS3DWB sensor bandwidth (2.4 kHz), digital I²C/SPI interface support, VDD/VDDIO dual-supply operation (1.71–3.6 V), interrupt pin functionality (INT1/INT2), and compatibility with STEVAL-MKI109V3/MKI109D host platforms and MEMS Studio GUI.
Technical Context
The STEVAL-MKI208V1K is a hardware evaluation interface-not a semiconductor component-and functions exclusively as a carrier for the IIS3DWB MEMS vibration sensor. It provides full access to all IIS3DWB pins via a standard 24-pin DIL socket, supports both I²C (SDA/SCL) and SPI (CS/SDO/SDA) communication modes, and includes dedicated interrupt outputs (INT1, INT2) routed to header pins.
Power delivery is split across VDD (1.71–3.6 V for core logic) and VDDIO (1.71–3.6 V for I/O), with onboard 100 nF and 1 µF decoupling capacitors. The board mates directly with STEVAL-MKIGIBV2 adapter and is fully supported by STM32F401VE-based STEVAL-MKI109V3/D host platforms running MEMS Studio firmware.

FAQ
Does STEVAL-MKI208V1K include the IIS3DWB sensor?
Yes. The STEVAL-MKI208V1K is a complete evaluation kit with the IIS3DWB 3-axis digital vibration sensor permanently soldered at the PCB center. No additional sensor purchase is required - the board ships fully assembled with decoupling capacitors, pull-up resistors, and interface headers ready for connection to STEVAL-MKIGIBV2 or compatible DIL24 hosts.
Which development platforms support STEVAL-MKI208V1K?
STEVAL-MKI208V1K is fully compatible with STEVAL-MKI109V3 and STEVAL-MKI109D evaluation platforms. Both feature an STM32F401VE microcontroller acting as a USB-to-sensor bridge and support MEMS Studio GUI for real-time data visualization, register configuration, and firmware scripting without custom driver development.
Can STEVAL-MKI208V1K operate standalone without a host platform?
No. The board lacks onboard processing, USB interface, or power regulation circuitry. It requires connection via cable to STEVAL-MKIGIBV2 (DIL24 adapter), which in turn plugs into STEVAL-MKI109V3/D or other compatible host platforms to provide power, clock, and serial communication - no standalone operation is possible.
What mounting options does STEVAL-MKI208V1K offer for vibration testing?
The board provides two mechanical mounting methods: (1) pre-applied double-sided adhesive tape for temporary, non-invasive attachment to flat metal surfaces of motors, pumps, or gearboxes; and (2) four M2.5 threaded mounting holes at each corner for permanent bolted installation under high-vibration conditions.
