The compass is a HONEYWELL HMC6343 with tilt capability, although we only use the heading information for our prototype.For Arduino Users
The compass' SDA Pin needs to be connected to Arduino Duemilanove's Analog Pin 4. The SCL is connected to the Analog Pin 5. We also used two resistor, both 4.7kΩ: The first connected to VCC and SCL. The second goes from VCC to SDA. Click on the image to see the full picture![](../../../../files/2010/12/compass_arduino-1024x612.png)
For DakaX Users
On the DakaX's the compass does NOT need two resistors, unlike the Arduino. Click on the image to see the full picture![](../../../../files/2010/12/IMAG0091_dakaXConnection1-1024x774.jpg)
