Hey guys, I've been working on following along with an Arduino project https://www.instructables.com/id/How-to-Build-a-GPS-Guided-Robot/ and apparently I've made a fairly common mistake in purchasing the QMC5883L Compass instead of the HMC5883L. The HMC was discontinued as of this year and the QMC …

Hi andrymyr, It depends on what QMC5883L device you have? There are two revisions of this chip: "A" and "B" that are totally different from each other. If serial number on the QMC5883L device is "DA5883" then the device is identical to the Honeywell HMC5883L, responds to the I2C addresss 0x1E, exc…

Any magnetometer chip intended for detecting the Earth's magnetic field will work, and several modules are available from Pololu, Sparkfun, Adafruit, etc. The only function it is used for in this application is to determine the robot's current heading relative to magnetic North. The important thing…

Any way to use HMC5883L library with QMC5883L

Use the QMC5883L library. The chip is not a clone, and not all HMC5883L sensor functions are available.

Don't forget to calibrate the sensor properly.
