SparkFun Micro Absolute Digital Barometer (LPS28DFW)

SparkFun Micro Absolute Digital Barometer (LPS28DFW) is a unique barometer breakout featuring the STMicroelectronics LPS28DFW. The SparkFun barometer is offered in the Qwiic Micro form factor. The LPS28DFW is an absolute barometer with a water-resistant package making it ideal for pressure measurement applications where the sensor is exposed to or submerged in water. The Qwiic system allows for integration into an I2C system, requiring no soldering. While the Micro size does not allow for a traditional 0.1"-spaced PTH header for communication, the board does route an interrupt and ground pin to a through-hole connection.
