STMicroelectronics has introduced the STEVAL-MKI109D a MEMS sensor evaluation board, designed to test and optimize STMicro’s MEMS sensors for various applications, including industrial automation, smart agriculture, and consumer electronics.
Built around the STM32H563ZI Arm Cortex-M33 MCU this development board features I²C, I3C, and SPI interfaces, along with a TDM interface for high-speed sensor data communication. The board is also compatible with STMicro MEMS DIL24 adapter boards, which makes it easy for engineers to test different sensors. Additionally, it has software-adjustable power circuitry (0–3.6V), and onboard power monitoring for accurate analysis of sensor performance.

The STEVAL-MKI109D board runs MEMS Studio, a no-code tool for evaluating and managing ST MEMS sensors. It includes Unico-GUI, Unicleo-GUI, and AlgoBuilder, providing an all-in-one solution for sensor configuration, real-time data visualization, firmware updates, and advanced analysis. You can explore operating modes, optimize power settings, and even integrate embedded AI features without writing code. Additionally, the board supports all ST MEMS DIL24 adapter boards, including accelerometers, gyroscopes, IMUs, barometric pressure sensors, and presence detection modules
ST’s MEMS portfolio includes inertial, pressure, biosensors, and microphones for industrial, consumer, and automotive applications such as smartphones, wearables, and driver assistance systems. Each sensor has an evaluation module on a DIL24 card for easy connection to the STEVAL-MKI109D, and a remote kit is available for off-board placement.
The STEVAL-MKI109D MEMS sensor evaluation board can be purchased directly from ST’s estore for $104.13. More information about the product can be found on the company’s announcement and product page.
