Pololu LPS22DF Pressure/Altitude Sensor Carrier with Voltage Regulator

This carrier for ST’s LPS22DF digital barometer measures pressures from 260 mbar to 1260 mbar (26 kPa to 126 kPa) with absolute accuracy down to ±0.5 mbar (0.05 kPa) and typical RMS noise of 0.0034 mbar (0.34 Pa) 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 1.8 V to 5.5 V, and the 0.1? pin spacing makes it easy to use with standard solderless breadboards and 2.54mm perfboards. The sensor offers I²C/I3C and SPI interfaces.
