The BMP280 Baro Sensor Module provides accurate altitude and air-pressure measurements for PX4 and Betaflight flight control systems. Designed for UAVs, FPV drones, and robotics, it delivers stable vertical positioning, improved altitude hold, and smoother flight performance in a compact, low-power package.
 
The BMP280 is a digital barometric pressure sensor from Bosch, widely adopted in professional and hobby-grade flight controllers. It enables reliable altitude estimation by measuring atmospheric pressure with high resolution and low noise, making it ideal for autonomous flight, altitude hold, and vertical navigation.
This module is fully compatible with PX4 Autopilot and Betaflight, requiring minimal configuration and integrating seamlessly via I²C interfaces.
