Tips for EMI MK Compass interference

Lipo lead mounting on CineStarWe have found the the mounting and orientation of the lipo has an effect on the MK compass. As seen in this image when you look at the NaviCTRL (arrow pointing forward) the compass (IC4) is located on the right edge. Route the main power lead off to the left from the pads on the power distribution ring.

Keep all power wiring short in length and bound together using zip ties ect. Also note that the lipo is mounted on the battery tray on its side. To further attenuate the magnetic interference some integrate an EMI shielding that is composed of tinned MU-copper. An example of this expandable diameter tubing:

The MU-copper shielding is installed on both the DC cable from the power distribution ring as well as the cables on the lipo battery. Special attention should be taken as the shielding is a very conductive material. All MU-copper shielding should have a complete shrink tube enclosure. A complete shielded assembly will look like this:
