Working great in Ardurover, easy setup

Plugged right in to Cube Orange with no modifications needed. Mission Planner detected (after 2 reboots) and enabled. Working much better than internal compass!
An excellent professional grade magnetometer

I have been building an autonomous lawnmower prototype using a Holybro Pixhawk 6x mini and a Sparkfun ZED-F9P RTK GPS module for GPS2 and had recently purchased a Holybro M10 GPS/Compass module for GPS1. The GPS portion of the M10 module is excellent, but I was less than satisfied with the noise immunity of the Compass portion which I am using for the Yaw heading. So I investigated the Holybro RM3100 Profession Grade Magnetometer, found its performance specs to fill my noise immunity requirements, and purchased one from GetFPV. I mounted the RM3100 module just behind the M10 module on the top of the lawnmower Control Module which put it directly over the lateral axis of the lawnmower differential steering motors. After calibration, I installed the Control Module on the lawnmower chassis, which even though it is a prototype is still much too big to go through a six axis compass calibration procedure, and found that it did not display the out of spec xy magfield message that the M10 module Compass had displayed. Even running the differential drive motors at full speed along with the cutting head DC motor did not cause an out of spec xy magfield message or drift in the magnetometer heading. Now all I need to do is see how the RM3100 maintains the Yaw heading while the lawnmower is in operation.
