Product overview


The STEVAL-MKI141V2 is an adapter board designed to facilitate the evaluation of MEMS devices in the HTS221 product family. The board offers an effective solution for fast system prototyping and device evaluation directly within the user’s own application.

The board also offers an example reference design for custom PCB implementation.

The STEVAL-MKI141V2 can be plugged into a standard DIL 24 socket. The adapter provides the full HTS221 pinout and comes ready-to-use with the required decoupling capacitors on the VDDpower supply line.

This adapter is supported by the STEVAL-MKI109V2 motherboard which includes a high-performance 32-bit microcontroller functioning as a bridge between the sensor and a PC, on which it is possible to use the downloadable graphical user interface (Unico GUI), or dedicated software routines for customized applications.

The STEVAL_MKI109V2 must be upgraded to eMotion V3.0.7 FW or later, and the Unico GUI must be rel. or later.

Note that to obtain accurate measurements, it is recommended to connect the STEVAL-MKI141V2 to the STEVAL-MKI109V2 using cables of 20-30 cm in length, in order to exclude any thermal effects from devices on the main board.
