Adafruit BMP280 Barometric Pressure & Altitude Sensor is a Bosch BMP280 breakout designed for accurate barometric pressure and temperature sensing, with altitude estimation based on pressure readings. It is the next-generation upgrade to the BMP085/BMP180/BMP183 family and is well suited for weather stations, portable instruments, and embedded sensing projects.
The sensor measures barometric pressure with ±1 hPa absolute accuracy and temperature with ±1.0°C accuracy. It can also be used as an altimeter with approximately ±1 meter relative accuracy, with low altitude noise quoted at 0.25 m. As with all pressure-based altitude calculations, real-world altitude accuracy depends on correct local sea-level pressure calibration.
This breakout supports both I2C and SPI, giving you flexibility in how you integrate it into a project. Use I2C for quick, simple wiring, or choose SPI when working with multiple sensors and you want to avoid I2C address conflicts.
The BMP280 is soldered onto a custom PCB in the STEMMA QT form factor, with STEMMA QT connectors on both sides for fast, solderless I2C connections using a compatible cable. These connectors are also compatible with SparkFun Qwiic ecosystems, making it easy to chain the sensor with other I2C boards.
All pins are also broken out to standard headers for conventional wiring. The board includes an onboard voltage regulator and level shifting, so it can be used with either 3.3V or 5V systems such as modern microcontroller boards and classic Arduino-compatible platforms.
Note: a STEMMA QT / Qwiic cable is not included. The included hardware information in the source covers the BMP280 breakout board itself.

For a typical I2C hookup, connect board 3V to VIN, GND to GND, SCL to SCK, and SDA to SDI. For SPI, use SCK, SDI, SDO, and CS as required by your controller and library.
The supplier guide provides example libraries and code for Arduino and CircuitPython, making this breakout a straightforward choice for both rapid prototyping and finished builds.
Important: altitude is derived from pressure, so you will need the current local sea-level pressure for the most accurate altitude readings.
This breakout measures barometric pressure and temperature, and its pressure readings can be used to estimate altitude. It is intended for applications like weather sensing and altimeter-style measurements.
Yes. The board supports both I2C and SPI, so you can choose simple I2C wiring or use SPI when you want to avoid I2C address conflicts in multi-sensor setups.
