The PCB has been designed in KiCad EDA 9.0 using the kicad-lkbd libraries and kbplacer.

You can preview the project files using KiCanvas directly in your browser and download the latest fabrication files for JLCPCB from the latest release.

The exported schematic is also available under output/schematics.

The plate has also been designed in KiCad EDA 9.0 using the kicad-lkbd libraries.

It is reversible, so you can choose to either have a wave pattern design shown or just a plain PCB plate. It can be used alongside another Keyboard PCB to create a full case by stacking:

  • Plate PCB (any direction)
  • Assemble Keyboard PCB
  • Reversed Unpopulated Keyboard PCB

Use the same parameters present in PCB Order to order the plate and bottom PCB, you can find the fabrication files in output/plate/fabrication/jlcpcb.

Be careful, JLCPCB may charge an extra fee for this PCB because it has "too many holes". You may want to prefer 3D printing a full case instead.

If you prefer to fabricate it by any other mean (such as laser cut acrylic), you can download their board outlines as DXF in output/plate/dxf.

Footnotes

  1. The "HASL (with lead)" option is extremely discouraged due to the risk of lead poisoning. We strongly recommend paying the premium for the "Lead Free HASL" option.
