Adafruit BMP390 Precision Barometric Pressure and Altimeter Module - I2C/SPI, STEMMA QT
The Adafruit BMP390 is a high-precision barometric pressure and altitude sensor module compatible with 3.3V/5V microcontrollers like Arduino, Raspberry Pi, and ESP32. Featuring Bosch’s latest MEMS sensor, it provides superior accuracy for environmental monitoring and altitude tracking applications.
Features
- High-precision Bosch BMP390 sensor with ±3 Pa (±0.25 m) relative pressure accuracy.
- Dual I2C (address 0x76 or 0x77) and SPI communication interface options.
- Integrated 3.3V regulator and level shifting for 3V/5V logic compatibility.
- Pre-soldered STEMMA QT / Qwiic connector for solderless plug-and-play connectivity.
- Wide operating temperature range from -40°C to +85°C.

The Adafruit BMP390 module integrates Bosch’s advanced BMP390L MEMS pressure sensor, offering significant improvements in precision and noise performance over previous generations like the BMP280 and BMP388. It operates on the principle of a piezoresistive sensing element, providing stable and accurate barometric pressure readings from 300 to 1100 hPa, which translates to an altitude measurement range up to 9000 meters.
The module includes essential signal conditioning, a 3.3V voltage regulator, and logic level shifters, making it directly compatible with both 3.3V and 5V microcontroller systems such as Arduino, Raspberry Pi, ESP32, and STM32 development boards. The pre-soldered STEMMA QT connector (compatible with SparkFun Qwiic) enables rapid, solder-free integration into I2C bus systems.
