Can I replace the DIYDrones-HMC5843 with Sparkfun-HMC5843

Posted by Alex on October 27, 2010 at 9:50pm

Hi All:

 

    I need to use the HCM5843 magnetometer in my project urgently. Howver, now in our DIYDrones store, it is out of stock.

 

    I am wondering Can I replace the DIYDrones-HMC5843 with Sparkfun-HMC5843?

 

    It seems that they are the same in terms of the output format and sensor chip. Only the apprearance is different.

 

    Any suggestion and information is appreicated.

 

    Thanks in advance.

 

Alex

    Hello, I need some help here about the magnetometer. I have a HMC5843 (the red board) from Sparkfun and I would like to reset de magnetometer to its factory default state, because after a setup error, the magnetomer gives me now bad values (I.e.: MagX:-32, MagY:32, MagZ:-32,)...
    Could someone can give me an answer here.
    Thanks for your help,

    It's the exact same sensor, so yes, of course you can.

    The only difference (for you) is that the DIYD unit has an onboard voltage translator - you won't be able to hook up the Sparkfun (3V) unit to a 5V Ardupilot directly. It would kill the sensor.
