A reduced size keyboard, but not quite 60%.
This is the extended version of the 59% keyboard.
- You can safely cut off the number pad section to remove the last 4 columns.
- Locate the two small ground pads at the top and the bottom of the board.
- Score along both front and back, and snap it off.
Finally fixed the missing trace on S05:1 - on the ones I built I just soldered on a wire to bridge the missing gap.
