Keyboard PCB RS-274X Design

I need a complete RS-274X (Gerber) package for a keyboard whose primary purpose is everyday typing. The PCB should follow a conventional matrix layout, ready to drive a standard USB-based controller.

Your job is to take my reference layout notes and turn them into:
• A clean schematic that reflects the key matrix, MCU, and USB-C interface I’ll supply.
• Layer-stacked PCB files in RS-274X format, including drill, solder-mask, silkscreen, and board outline.
• The editable project file (KiCad or Altium—whichever you prefer) so future revisions are straightforward.

I haven’t locked in the switch type yet, so feel free to route with clearances that would suit either mechanical hotswap sockets or a simpler through-hole footprint; your advice here is welcome.

Acceptance criteria
• Gerbers load error-free in common viewers (Gerbv, ViewMate).
• All nets pass DRC against a 2-layer, 6 mil/6 mil, 0.3 mm via spec.
• USB differential pairs length-matched within ±0.2 mm.

If you can deliver a production-ready RS-274X set that meets those checks, let’s get started.
