Description: Replacement: None. We are no longer carrying this tilt compensated compass in our catalog. This page is for reference only.

The LSM303DLH is a triple axis MEMS accelerometer combined with a triple axis magnetic sensor. The sensor has an easy to use I2C interface. Supply voltage should be between 2.5 and 3.3 VDC.

Check below for a breakout board!


  • +- 2/4/8 g dynamically selectable full-scale
  • +-1.3 to +- 8.1 gauss magnetic field full-scale
  • 16-bit data out
  • I2C interface
  • Embedded self-test


Customer Comments

  • It looks like there is a library on GitHub to turn this into a tilt compensated compass:
    I haven’t tried it out though. I’ll add this part to my wish list :)

  • This is NOT a tilt compensated compass. This is a bundle of sensors that can be used to make a tilt compensated compass. There’s lots of computation involved in going between magnetometer readings and compass readings (see the app note).

  • Impressive, the 430 units ran out of stock in few hours…
    I know there is a penury with that chip.

  • Are you guys getting more of these? They’re nowhere to be found.
    And combined with the HMC5843 EOL.. it could be a tough couple months for UAV nerds. :-\

  • I know what I’m spending my freeday money on. Sparkfun read my mind!

  • How does this compare to the pricey HMC6343?

    • This doesn’t output heading in degrees or pitch/roll in degrees. The HMC6343 does. The HMC6343 also has a built in temperature sensor if I’m reading the datasheet right.
      In my opinion, the LSM303 should be should be called a “3-axis accelerometer and 3-axis magnetometer” because of this. You can use it to get pitch, roll, and heading.. but you need a uC to do some maths to get these values (the diydrones site and the app note on this page have helpful information on calculating this).

      • Oh I see, so this is outputs pure magnetic-magnitude-per-axis then? Thanks for the help
