The new magnetometer works perfectly as a breakout board. We just could not place it by hand. It has less noise than the MPU9250 and also seems to be faster. I have it working on the present version of the circuit board and I am using the MPU9250 tilt sensor. So the Memsic tilt sensor will be the next piece to add as a breakout board, then we will be done with testing and move on to the final version of the all in one circuit board.
