KAmodLPS331

Description

KAmodLPS331 is a module, which bases on absolute pressure sensors LPS331. It is characterized by i.a. wide range and high resolution of measurement. Module allows to measurement of absolute pressure in range 260 - 1260hPa. Thanks to embedded voltage regulator and logic level translator, module can be used in system with power supply 2.5 - 5.5V.
