  • Short on documentation.

    posted by sworteu

    Can be aimed towards the sky. Is very easy to mount. Comes with all you need except for documentation (a cd is there but it doesn't tell you how to connect).
    Connection documentation is:Red: 5voltTiny Black: GNDThick black:Unknown (please let me know!)White: Tx (put this in a serial RX)
    Could be better, but i must say it works. However it's hard to know exactly how to connect it and make it work perfectly if some wires are unknow.
  • Very useable magnetometer

    posted by ggutshal

    Very small form factor. I2C interface so it doe not consume too many IO pins. The HMC5883 magnetometer is a pretty standard part in the microcontroller/robotic community. Libraries exist for arduino and netduino
    Should be very useful for robotics, unmanned aerial vehicles or other implementations requiring the detections of orientation. Alternatively this module could be used in any application that calls for a highly sensitive 3d magnetometer.
  • Good Basic Navigation Board

    3 axis compass as well as accelerometer on a single board with a simple I2C interface. Easy to interface with Arduino - library code is available if you google for the chip numbers. 3 axis sensitivity allows you to mount it in any orientation.
    Compass is very sensitive and care needs to be taken in selecting a mounting position. Speaking from experience, it is not a good idea to mount it directly above the drive motor of your robot.
    A usable module for basic navigation.DRY pin on board is the Data Ready pin on the compass chip.
  • good choice

    Simple breadboard with HMC5883L compass, which is accessible using I2C and can manage 5V on I2C buss.Breadboard has 5V -> 3.3V regulator so no external component is required.HMC5883L is well supported by Arduino libraries but it's no problem to write own routines.
    Good for any DIY project which needs compass navaigation.
    It is 3 axes magnetometer, it means that you get 3 values for each axes and it's up to you to count the bearing.
