SparkFun Barometric Pressure Sensor Breakout - BMP180 (with Headers)

This is a breakout board for the Bosch BMP180 high-precision, low-power digital barometer. The BMP180 offers a pressure measuring range of 300 to 1,100 hPa with an accuracy down to 0.02 hPa in advanced resolution mode. It’s based on piezo-resistive technology for high accuracy, ruggedness and long-term stability. These come factory-calibrated, with the calibration coefficients already stored in ROM.

This version of the SparkFun Triple Axis Accelerometer Breakout includes pre-soldered male headers for ease of use. With the headers already soldered on, you can jump right into using this little board without any assembly!

The breadboard-friendly BMP180 breaks out every pin to a 5-pin 0.1" pitch header. VCC can be from 1.8V to 3.6V and is I/O lines are 5V tolerant; we typically run it on a clean, regulated 3.3V supply. The analog and digital supplies (VDDD and VDDA) are tied to a single header pin, but are separately decoupled. It connects to a microcontroller via I²C bus (also known as TWI, or on the Arduino, the “Wire” library).

Note: Since this product belongs to our “Ding and Dent” category, once we are out of stock we will not carry it again. Get them while you can!

SparkFun Barometric Pressure Sensor Breakout - BMP180 (with Headers) Product Help and Resources

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

3 Programming

Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Customer Comments

  • Do not understand this as a “new” product because distributors no longer carry BMP180 and indicate it is obsolete.

    • What Mike said, it is the headers that make this board new. We also built these up for a kit a while back and then just before we went to go live with the kit got the EOL notice on the BMP180. We swapped out the sensor in the kit, but still had these built. We are starting to look into selling more boards with headers in the long term, but once these are gone their gone.

    • Good eye! This board is listed as “new” because we pre-soldered headers to it. We’ve traditionally left this up to the customer, but we’ve had a lot of requests from teachers who want to use these in their classrooms (the BMP180 is a great sensor) but don’t have the skills or time to solder headers to them.
