ST offers a modular dual-board configuration for easy access to sensor features such as device configuration, acquisition, data logging, and to view and modify device settings. The STEVAL-MKI109V2 is a STM32 USB-based main board which supports the pressure sensor as well as many other MEMS devices. The STEVAL-MKI120V1 is the LPS331 pressure sensor plug-in module as shown on this slide. ST also provides the low level device drivers, and a simple to use GUI which runs in Windows XP or Win7. LPS25 and HTS221 adapters will be available in the near future.
