Finally got my compass sort of working, well it doesn't give of it's standard direction of 45 degrees it used to give of. It actually changes, its giving of the actual direction its facing, but it only works for a very short time. After that it sort of crashes ARC... It stays stuck in "connected" while the LED on the EZ-b is pulsating, like it's not connected. So I think it's browning out my EZ-b... I'll try powering it from an alternative powersource.

I'm using 2k resistors. And made a board for it.

Hi all, does anyone have a update to this thread? I have my sure electronics compass working, but it is less then I hoped it would be. North never seems to be quite right and west and east will sometimes switch. I'm guessing interference is the problem, but I have also read in other post that I can try either a pull up resistor to ground or +5 volts. My robot is fairly compacts so I'm hoping to find something that will be a little less sensitive to the interference and have better accuracy. @Robotmaker did you have any luck with your test on the other 3 compass modules?

Try the pull-up resistors, I've read in other topics that some sensors which were not working at all start working when pull-ups are installed.

Compass modules will be susceptible to interference so relocating it may be an idea.

@RobotMaker no longer frequents the forum. @MovieMaker and a few others are in contact with him still I believe, perhaps they could ask?

Thanks for the update Rich, I will give the resistors a shot. I've been out of the scene for over a year as well. The new V4 board and EZ-bit robots got my attention back though. My little guy is starting to get interested in robots too so that helps
