A new guide is in the Adafruit Learning System on Adafruit’s new BMP388 – Precision Barometric Pressure and Altimeter breakout board.

Bosch has been a leader in barometric pressure sensors, from the BMP085. BMP180, and BMP280… now we’ve got the next generation, the Adafruit BMP388 Precision Barometric Pressure sensor. As you would expect, this sensor is similar to its earlier versions but even better. The BMP388 has better precision than ever, which makes it excellent for environmental sensing or as a precision altimeter. It can even be used in either I2C and SPI configurations.

The BMP3xx is the next-generation of sensors from Bosch, and is the upgrade to the BMP280 – with a low altitude noise as low as 0.1m and the same fast conversion time. And like the previous BMP280, you can use I2C or SPI. For simple easy wiring, go with I2C. If you want to connect a bunch of sensors without worrying about I2C address collisions, go with SPI.

Sensor and breakout information is included as well as sample code and libraries for Arduino and CircuitPython. Get up and running quickly and easily on microcontrollers or Single Board Computers using the BMP388 with this new guide.
