Here you will find all the construction details for each of the boards in this project which I will actively maintain to include the latest revision of boards and documentation.
I’m not going to hand-hold you though the construction of these boards. They have PCB foils and most have schematics. It’s pretty much up to you to source the correct components and do the assembly, configuration etc. If there is anything that you are end up stuck on drop me a line and I’ll try to help, but the assembly of a project like this is a complicated affair so you need to know what you’re doing.
