BMP280 Digital Barometric Pressure & Altitude Sensor Module (I2C/SPI)

Overview

The BMP280 is a high-precision digital barometric pressure and altitude sensor module designed by Bosch. Supporting both I2C and SPI digital interfaces with ±1 hPa absolute accuracy (corresponding to ±1 meter altitude resolution), it is the primary choice for drone altitude-hold systems, weather stations, and sports trackers.
