The BMP390L has better precision than ever, which makes it excellent for environmental sensing or as a precision altimeter. It can even be used in either I2C and SPI configurations.

This sensor has a relative accuracy of ±3 Pascals, which translates to about ±0.25 meters of altitude (compare to the BMP280's ±12 Pascal/±1 meter and BMP388's ±8 Pascal/±0.5 meter).

The surface-mount sensor is soldered onto a custom made PCB in the STEMMA QT form factor, making them easy to interface with. The STEMMA QT connectors on either side are compatible with the SparkFun Qwiic I2C connectors.
