This kit comes with:

• PCBs for left and right halves

• 47 1N4148 diodes

• 2 reset switches

• 2 TRRS jacks

• 2 Switch plates

• 2 Bottom plates

• 28 M2 6mm screws

• 14 M2 10mm standoffs

Plates for the Fourier are:

• FR-4 PCB material

  • 1.6mm PCB material (FR-4)

  • Black

To complete a kit you will still need:

• MX or Alps compatible switches

• Keycaps

• 2 Arduino Pro Micro or other micro controller (elite c, nice!nano, etc…)

• TRRS cable

• Micro USB cable or USB C (if using elite c or similar)

• PCB-mount MX stabilizers
