Description: Freescale’s MAG3110 is a small, low-power, digital 3-axis magnetometer. The device can be used in conjunction with a 3-axis accelerometer to produce orientation independent accurate compass heading information. It features a standard I2C serial interface output and smart embedded functions. It’s also a tiny QFN package which isn’t very easy to play with so here is our easy to use breakout board. This board breaks out all of the pins for the MAG3110 to a standard 0.1" header and also supplies the necessary filtering capacitors so that you can easily use it in your next navigation project.


  • 1.95V to 3.6V Supply Voltage
  • 7-bit I2C address = 0x0E
  • Full Scale Range ±1000 μT
  • Sensitivity of 0.10 μT
  • Pull Up Resistor Jumper

Dimensions: 13.3 x 14.5 mm

  • Hey guys, just a heads up that there is a error in the coordinate system marked on the breakout. On the top side, the z-axis points down. On the bottom silk screen, the z-axis is drawn correctly, but the arrow for x is mirrored from the correct orientation! Handy breakout, but this did cause some confusion when looking at the sign of some of the data. Thx!

  • Is see that this is an update to the SEN-10619 MAG3110 breakout, which no longer is available. Aside from making the I2C pull-ups optional, the features of this version 12 breakout are the same as the prior version 11. So why did you change the pinout? Keeping the pinout the same would have let me use this version-12 breakout on my 35 circuit boards, which are designed for the version-11 pinout.

  • Is there something particularly appealing about this magnetometer I am missing? It only have a FSR of 10 Gauss and is sensitive to 1 milligauss, which doesn’t seem to be competitive with other current MR(I am guessing based on the need for a reset current) parts with similar power consumption.

  • How about an inexpensive board with both the accerometer, and magnetometer?

    • check out our IMUs, I believe we have a few 9DOFs (also have a gyroscope) on a single chip that are pretty cheap.
