motherboard

The STEVAL-MKI109V2 is a motherboard designed to provide users with a complete,

ready-to-use platform for the demonstration of STMicroelectronics’ MEMS products. The

board features a DIL24 socket to mount all available adapters for both digital and analog

output MEMS devices.

The motherboard includes a high-performance 32-bit microcontroller, which functions as a

bridge between the sensor and a PC, on which it is possible to use the downloadable

graphical user interface (GUI), or dedicated software routines for customized applications.

STEVAL-MKI120V1 LPS331AP adapter

The STEVAL-MKI120V1 adapter board is designed to facilitate the demonstration of the

LPS331AP product. The board offers an effective solution for fast system prototyping and

device evaluation directly within the user’s own application.

The STEVAL-MKI120V1 can be plugged into a standard DIL 24 socket. The adapter

provides the complete LPS331AP pinout and comes ready-to-use with the required

decoupling capacitors on the VDD power supply line.
