The Zen 2 keyboard kit includes:
PCBs, FR4 plate, screws, nuts, TRRS jack and springpins
2 PCBs. Top, middle, and bottom are included.
2 Optional type-C (TYPE-C-31-M-12) ports (difficult to solder)
66 100NF 0805 capacitors
66 SK6812 or WS2812b RGB LEDs
16 2x1 2.54mm Pin headers
66 Switches, MX or Choc
10 M2.5 x 5mm standoffs for MX builds only (recommended to help assembly) Hex must be <5.2mm wide.
(Optional) 2 Rotary encoders
TRRS or Type C cable for interconnect
Keycaps, any Ergodox-compatible set will work.
The Type-C ports are difficult to solder. Screwing them up can result in damage to your controller. Only proceed if you can test the board after soldering and make sure there are no shorts.
MX switches which support SMD LEDs will give the best backlighting effect. Almost all Kailh switches have a cutout for the LED. Kailh BOX/Choc switches will not be able to have their tops opened after soldering. Any switch with a transparent bottom housing will work great.
