Hint: If you are designing your own PCB make sure to align the pin1 marking of your BHA250B and the Magnetometer of your choice in the PCB layout for plug-and-play axis alignment of your system. Following this recommendation ensures a proper absolute orientation out of the box without the need of a subsequent axis remapping of the x, y and z-axis of BHA250B and the Magnetometer. Regarding landing pattern design and connection diagrams please refer to the corresponding product data sheets of the devices.
Using the Development Desktop environment and the dedicated BHA250B shuttle boards which already include the 4 different Magnetometers, you can easily run our shark UI demo to test all 4 eCompass solutions at once.
