Making Stuff Together! / Re: Stupid quick PCB design

I do believe we have a slight misunderstanding. This is the controller I currently have. I am going to use them for a custom hand wired keyboard that will not have a traditional case, but more of an open frame chassis. The purpose of the PCB I am wanting to make is to have something to solder my controller to and be able to physically attach it to the keyboard frame with stand offs and 6-32 thread screws.
