Pressure sensor evaluation boards

UNICO/eMotion evaluation system: [STEVAL-MKI109V2] + [STEVAL-MKI142V1 or V2].

Figure 1. STEVAL-MKI142V1 LPS25H adapter, STEVAL-MKI109V2 MEMS 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 DIL 24 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) from ST (Unico SW), or dedicated software routines for

customized applications.

A plain terminal (such as MS windows hyper-terminal (C)) can also be used to access the

sensor registers by text read/write commands.

Figure 2. STEVAL-MKI142V1 - LPS25H adapter

The STEVAL-MKI142V1 adapter board is designed to facilitate the demonstration of the

LPS25H product. The board offers an effective solution for fast system prototyping and

device evaluation directly within the user’s own application.

The STEVAL-MKI142V1 can be plugged into a standard DIL 24 socket. The adapter

provides the complete LPS25H pin-out and comes ready-to-use with the recommended

decoupling capacitors on the VDD power supply line. No pull-ups are provided.
