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.
