Guide Updated: Adafruit BMP388 and BMP390 – Precision Barometric Pressure and Altimeter #AdafruitLearningSystem #Adafruit #CircuitPython @Adafruit

It’s the BMP390 with STEMMA QT!

The BMP3xx is the next-generation of sensors from Bosch, and is the upgrade to the BMP280 – with a low altitude noise as low as 0.1m and the same fast conversion time. And like the previous BMP280, you can use I2C or SPI. For simple easy wiring, go with I2C. If you want to connect a bunch of sensors without worrying about I2C address collisions, go with SPI. The BMP390 includes STEMMA QT connectors for easy no-soldering-necessary inclusion in your project!

The Adafruit BMP388 and BMP390 – Precision Barometric Pressure and Altimeter guide is now updated to include info on the BMP390, including wiring diagrams and resource downloads. The pinouts match, so it’s an easy drop-in replacement for your current project if desired!
