STEVAL-MKI222V1 is an adapter board designed to facilitate the evaluation of MEMS devices in the LIS2DU12 product family. The board provides users with an effective solution for rapid system prototyping and device evaluation directly in their own applications. STEVAL-MKI222V1 can be plugged into a standard DIL 24 socket, offering the complete LIS2DU12 pin layout with the required decoupling capacitors embedded on the VDD supply line. The adapter board is fully compatible with the STEVAL-MKI109V3 motherboard, which incorporates a high-performance 32-bit microcontroller that acts as a bridge between the sensor and a PC. Users can operate it via the Unico-GUI graphical user interface downloaded from www.st.com (STSW-MKI109L for Linux, STSW-MKI109M for Mac OSX, or STSW-MKI109W for Windows), or via a dedicated software program for custom applications. Plugging the adapter board into the X-NUCLEO-IKS01A3 expansion board enables users to develop their own applications.
