The project was devised to take advantages of the features that were available on the Azure Sphere board, namely the GPIO and UART. For more details of the electronics, see Element14. As the project stalled due to the immaturity of the SDK at the time, it was shifted over to an Arduino MKR board and written up as the Getting your bearings project for Diyode magazine. The compass also formed the central topic of a talk about the Joy of Making given to the Microsoft Garage in Prague.
