Hello, I'm looking for any custom keyboard/pcb that requires the components to be soldered directly to it, and uses a atmega32u4. I happen to have a promicro board that I ripped the USB connector and traces from it, so with this new spare chip I was looking to try building something :)

I know most PCBs that can be bought will come with the components already soldered, but I'm open to protects where the pcb needs to be send to be manufactured.
