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.

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
