What could be next steps for this project? I am planning to make a PCB for the project. I am learning KiCad and started work on the schematics. A first version of the schematics can be found in the files section of this project. I am not sure how to add the Mega 2560 and SDCard shield functionality to the PCB though. Also the Emic 2 will have to stay separate, right? It will be a good learning project for me.
