This breakout board is for the Bosch BMP180 (replaces the BMP085) high-precision digital pressure sensor. The BMP180 measures a pressure range of 300 - 1100hPa.

The BMP180 is the function compatible successor of the BMP085, a new generation of high precision digital pressure sensors for consumer applications. The ultra-low power, low voltage electronics of the BMP180 is optimized for use in mobile phones, PDAs, GPS navigation devices and outdoor equipment.

With a low altitude noise of merely 0.25m at fast conversion time, the BMP180 offers superior performance. The I2C interface allows for easy system integration with a microcontroller. The BMP180 is based on piezo-resistive technology for EMC robustness, high accuracy and linearity as well as long term stability.

The 662K regulator converts input voltage from 5 to 3.3V to 3V regulated output for sensor. The I2C interface can work with 3.3V or 5V MCU. So you can use the board with either 5V system or 3.3V system.


  • Supply Voltage: 3.3V - 5V
  • Pressure Range: 300 - 1100hPa (+9000m to -500m)
  • Interface: IIC (Max 3.4 Mhz)


  • Indoor navigation
  • GPS-enhancement for dead-reckoning, slope detection, etc.
  • Sport devices, e.g. altitude profile
  • Weather forecast
  • Vertical velocity indication (rise/sink speed)
