Creating a PCB for my MCU
Get a piece of software such as Fritzing, EAGLE, or gEDA where you can create the schematic with the components you need and create the PCB layout once complete. You then send the files (or their exported equivalents) to a PCB fab that will create the PCB for you for a price and post back the results. You can then either solder the components on yourself or send them along with the PCB to an assembly service.
