Adafruit BMP280 I2C or SPI Barometric Pressure Altitude Sensor - Assembled

The BMP280 from Bosch is a precision barometric pressure and temperature sensor, and the next-generation upgrade to the BMP085/BMP180/BMP183 family. With support for both I2C and SPI communication, it offers flexibility for a wide range of weather sensing and altitude estimation projects. This version comes fully assembled with headers pre-soldered for immediate breadboard use.

With ±1 hPa barometric pressure accuracy and low altitude noise of 0.25 metres, the BMP280 delivers reliable environmental readings suitable for weather stations, altimeters, and IoT applications. The breakout board includes a 3.3V regulator and level shifting for easy use with both 3V and 5V microcontrollers.

Key Features
