Good catch. I was curious why my fine angle knippers were struggling and had to be re-sharpened, when I tried to clip the excess from some headers. So.... #1 buy good solid brass headers, #2 do not use the headers that come with your cheap sensors, #3 if in doubt - use the magnet. Check any wire terminal ends too. I just checkes some of mine after this video, and turns out my wire connect terminals were ferrous also. My mistake, I have the super-awesome molex brand, but just used a cheap cable in my box of stuff. Steel header pins is Japan's "thank you" back to the USA for dropping the bomb.
This is true, I tried to use this thing to measure magnetic field angle before, but the breadboard got pulled and sticks to the magnet. After that the reading was off and it made me confused as hell. Then I tried to pull the sensor out of the breadboard and just connect it directly to the microcontroller and the reading was good again. I guess the breadboard got magnetized somehow.
TWO questions: 1) did you leave a product review on Ebay about the magnetic header pins? This had not even occurred to me, btw! 2) With NO mag sensor, can you power up a drone @ 0° degrees using a real compass and have GPS work accurately based on booting it positioned on the ground @ true north?
Mine is L883 chip which is actual hmc5883l but still it's not working. I'm just getting the board info as output. What could be the issue? I'm sure about the connections. Running it with Arduino nano
hey, I have used them before and I had so many issues with them. the data just become off and jump from north to south. what did you do to solve that problem?
Keep in mind when working with these to keep all metal away from them, even the header pins which I mention in this video should be checked to see if they are magnetic. Check your wire too to make sure it is not magnetic. Also, remember that motors and other electronic equipment can give off Interference, mount the compass as far away from the motors as possible! Also, all of these magnetometers need to be calibrated if you want them to work properly. Brainy-Bits has an excellent video on how to do this. Its called, "Let's build an Arduino electronic Compass", make sure you use the correct Arduino Library to do this. Good luck!

Thanks for letting me know! I avoided using the header pins because of your video! Thanks
Superb hint! Thanks!

Thank you for the heads-up
Wow! But of course! Never came to my head!
thanks it works!

Anyone have this problem with the MPU9250? Noticed some MPU9250s are sold with ferrous pin headers. Can't seem to calibrate those ones correctly.

@@EZtech Thanks!
I have a bn880 gps believe the metal shields of the gps are magnetized... now using gy-271 with wires direct solder
Could you provide or suggest a solution?
You can use solid copper wire strains from a thick wire
