El Duderino Introduction
The SparkFun Absolute Digital Barometer - LPS28DFW (Qwiic) (Standard Size and Micro Size) offer a unique barometer breakout featuring the LPS28DFW from STMicroelectronics©. The LPS28DFW is an absolute barometer with a water-resistant package making it perfect for pressure measurement applications where the sensor is exposed to or even submerged in water1.

The sensor has two full-scale measurement ranges of 260 - 1260hPa and 260 - 4060hPa with an absolute pressure accuracy of 0.5hPa. The LPS28DFW is composed a piezoresistive pressure sensor with a metal lid and gel encasing to protect the sensing elements from water and other environmental hazards.
In this guide we'll cover the features and specifications of the LPS28DFW and other hardware present on these Qwiic breakouts as well as the Arduino library we have written to interact with the sensor.

Important! While the LPS28DFW is protected from water, the rest of the components on these breakouts are not protected by any conformal coating and can be damaged by exposure to liquids. Users who intend to use these breakouts in applications where the board may be exposed to water or other liquids should apply conformal coating to the board prior to use.
Required Materials
To follow along with this guide you will need a microcontroller to communicate with the LPS28DFW. Below are a few options that come Qwiic-enabled out of the box:
