A guide to building the Zygomorph keyboard, available at RGBKB.
Zygomorph keyboard PCB
Included M2.5 x 5mm screws, nuts, and pin headers
A case, plate or CNC
Switches: MX or Kailh Choc (24-30 per half)
MX switches require a plate when used with the CNC case
Keycaps, ortholinear. The backlit Choc keycaps kit has enough 1u keys.
Type C cables, one for the PC and one to connect the halves
Your interconnect cable must be data transfer capable
The PC cable should be at least 3A capable for full brightness
Feet: Rubber sheet or pads
(Optional) Rotary Encoder, most marked for Arduino will work, no PCB
Be careful of the 3 springpins on the underside of the switchboard, they bend easily. If they are bent down, the may need to be bent slightly up to make contact with the LED board.
MX switches which support SMD LEDs will give the best backlighting effect. Almost all Kailh switches have a cutout for the LED. All Kailh Choc low profile switches also have a cutout for the LED. Kailh BOX/Choc switches will not be able to have their tops opened after soldering. Cherry and Gateron have a lineup of RGB switches. Any switch with a transparent bottom housing will work great.
