Overview

This is a 24-bit high precision barometric pressure sensor, which allows accurate altitude tracing, as well as barometric pressure / temperature measuring. It supports both I2C and SPI interfaces, also is compatible with 3.3V/5V voltage levels.
Due to its ultra small form factor, low power consumption, low noise and high precision, the BMP388 Barometric Pressure Sensor is suited for applications such as drones, accurate altimeter, environment monitoring, and IoT projects, and so on.

Features

Supports I2C (default) / SPI interface
Onboard voltage level translator, compatible with 3.3V/5V operating voltage
Comes with development resources and manual (examples for Raspberry Pi/ /STM32)
