  • Hi! How do I exactly change the voltage from 3.3v to 5v? Add more solder on the left and remove the extra solder on the right side of the magneto jumper? Any help would be appreciated. Thanks.

  • Is it possible to get the eagle layout for this magnetometer??

    Even for attach it with cable, you will need to change the jump, because the EM406 connector share the same +5V power line.
  • @ sandro

    i noticed that the solder jumper on the mag is still on 3.3V. I've read here that we have to change the jumper to 5V if connected to the I2C port at the back of that port. may i know if the "no gps" port is 3.3V? thank you
