Product Description

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 0.1? perfboards. The sensor offers I2C/I3C and SPI interfaces.

This board is a compact (0.4? × 0.8?) carrier for ST’s LPS22DF MEMS absolute pressure sensor, or barometer; we therefore recommend careful reading of the LPS22DF datasheet (1MB pdf) before using this product. The LPS22DF is a great IC, but its small, leadless, LGA package makes it difficult for the typical student or hobbyist to use. It also operates at voltages below 3.6 V, which can make interfacing difficult for microcontrollers operating at 5 V. This carrier board addresses these issues by incorporating additional electronics, including a 3.3 V voltage regulator and level-shifting circuits, while keeping the overall size as compact as possible. The board ships fully populated with its SMD components, including the LPS22DF, as shown in the product picture.

The LPS22DF features embedded temperature compensation and has many configurable options, including selectable averaging, a choice of output data rates, several FIFO operating modes, and a programmable external interrupt signal. Its pressure output has an absolute pressure accuracy over temperature as low as ±0.5 mbar (0.05 kPa), with RMS noise of 0.0034 mbar (0.34 Pa) with maximum averaging and embedded filtering enabled. Pressure and temperature sensor data, which can be used for altimetry, are available through a digital interface configurable to operate in either I2C (TWI) or SPI mode. (See the Sample Code section below for an Arduino library that can be used to turn this sensor into an altimeter.) The MIPI I3C protocol is also supported on the I2C pins.

Dimensions: 0.4? × 0.8? × 0.1? (10 mm × 20 mm × 3 mm)
Weight without header pins: 0.5 g (0.02 oz)
Operating voltage: 1.8 V to 5.5 V
Supply current: 1 mA
Output format (I2C/SPI): 24-bit pressure reading (4096 LSb/mbar)

Included components

A 1×8 strip of 0.1? header pins and a 1×8 strip of 0.1? right-angle header pins are included, as shown in the picture below. You can solder the header strip of your choice to the board for use with custom cables or solderless breadboards, or you can solder wires directly to the board itself for more compact installations.
