This is a simple breakout board for the BMP085 high-precision, low-power barometric pressure sensor.

The BMP085 offers a measuring range of 300 to 1100 hPa with an absolute accuracy of down to 0.03 hPa. It's based on piezo-resistive technology for EMC robustness, high accuracy and linearity as well as long term stability. This sensor supports a voltage supply between 1.8 and 3.6VDC. It is designed to be connected directly to a micro-controller via the I²C bus


This board breaks out all pins of the BMP085 to a 4-pin 0.1" pitch header and also features put two 10k pull-up resistors on the I2C lines.



  • Digital two wire (I2C) interface
  • Wide barometric pressure range
  • Flexible supply voltage range
  • Ultra-low power consumption
  • Low noise measurement
  • Fully calibrated
  • Temperature measurement included
  • Ultra-flat, small footprint
  • Supplied with sensor cable (240mm)


  • 15.2 x 15.2mm

Using this for AVR/Arduino. Works as expected.

Replaced the pull-ups with 4.7k as I use it as the only device on an I2C bus. Else the 10k are too high.
Would have been nice to have at a 3.3V voltage regulator and 5V to 3.3V I2C wire 'translation' on board (cent items on volume). As PRODUCT ID: 381000109 doesn't have that either - this was the better deal for me.
