This is a prototype PCB (sent to http://dirtypcbs.com on 27/3/2016), designed and rendered with KiCad:

Some features:

  • 3/4“ key spacing
  • 7×5 positions for keys from which one may choose (1/2 x 3/4” spacing)
  • MX switch footprint that should match all possible (known to me) key variants (ignoring all features like diodes or LEDs)


Let there be “dirty PCBs”! Got 11, who wants some?
