LPS331AP Pressure/Altitude Sensor Carrier with Voltage Regulator
This carrier for ST’s LPS331AP digital barometer measures pressures from 260 mbar to 1260 mbar (26 kPa to 126 kPa) with absolute pressure accuracy over temperature down to ±2 mbar (0.2 kPa) and typical RMS noise of 0.02 mbar (0.002 kPa) in high-resolution mode. These pressures can easily be converted to altitudes. The board has a 3.3 V linear regulator and integrated level shifters that allow it to work over an input voltage range of 2.5 V to 5.5 V, and the 0.1″ pin spacing makes it easy to use with standard solderless breadboards and 0.1″ perfboards. The sensor offers I²C and SPI interfaces.
