For those who prefer something permanent rather than the clumsy Mikro Bus Interface module I had made, I am adding schematic and board design files for the interface module which only would require you to solder the standard headers to make something permanent. 

- Supports Waveshare/GoodDisplay 2.9" Display Module (0.1" Headers pre soldered on the Module)

- Supports two Waveshare/GoodDisplay 4.2" Display Modules (2mm headers pre soldered on the modules) Provided that Microsoft releases an update to the spi lib for Azure Sphere so that you can define a custom pin as CS pin.
