BMP388 Digital Pressure Sensor Module

The BMP388 Digital Pressure Sensor Module is a high-accuracy barometric pressure and temperature breakout based on the Bosch BMP388. It offers significantly improved performance over its predecessors (BMP180, BMP280) with lower power consumption, higher resolution, and faster sampling — making it well suited for altitude tracking, weather monitoring, and drone navigation.

With a relative pressure accuracy of ±0.08 hPa (equivalent to approximately ±0.66 m altitude difference), the BMP388 enables precise altitude and floor-height detection. It communicates via I2C (5V tolerant) or SPI (3.3V only on non-I2C pins) and is compatible with Arduino.
