Adafruit BMP390 Precision Barometric Pressure and Altimeter - STEMMA QT / Qwiic

The Adafruit BMP390 Precision Barometric Pressure and Altimeter Breakout is Bosch's next-generation sensor that offers superior precision for environmental sensing and altitude measurement.

Key features include:

• High precision with relative accuracy of ±3 Pascals, translating to about ±0.25 meters altitude resolution.
• Dual interface support for I2C and SPI allowing flexible connectivity options.
• Low altitude noise as low as 0.1m for stable altitude measurement.
• Compatible with 3.3V and 5V logic microcontrollers due to on-board 3.3V regulator and level shifting.
• Packaged in the STEMMA QT form factor with easy-to-use connectors for solderless connections and sensor chaining.
• Temperature measurement with ±0.5°C accuracy.

This breakout is ideal for drones, quadcopters, wearables, and any project requiring precise altitude tracking or environmental sensing.

The breakout PCB features updated visual design for better silkscreen readability and comes with black or tan STEMMA QT connectors.
