Half-keyboard optimized for gaming.

• 31 regular MX or KS-33/27 switches
• 5-way switch
• 3 push buttons
• per-key LEDs
• 3D printed case

Optimized for regular WASD setup similar to a normal keyboard, to avoid (or at least minimize) remapping keys for games.

No layer-tap and mod-taps to avoid conflicts (many games require mod presses or holding alpha keys).

1 additional layer to access missing half of keyboard.

Anyway it's easy to change keys on the fly with VIAL.

Tested on JLCPCB resin printing, it may be a bit tight for FDM.

• source code
• pre-compiled file

• PCB
• 3D printed parts (top, bottom, knob)
• Waveshare RP2040 Zero MCU
• 39 SMD SOD-123 1N4148 diodes
• 1 5way switch
• 3 push buttons - default height is 4.3mm but you can use 6-8mm if you want easier access to them
• 31 RGB LEDs
• M2 screws with flat head - 8mm for MX or 8mm+6mm for KS
• M2 nuts
• 7x1.5 legs

Please see my stront guide for detailed instructions on soldering diodes/LEDs/sockets/MCU.

Updated BOM:

• MCU - ProMicro pinout, bottom pins are needed for I2C and LED only
• 1.47" bare LCD with VIK adapter (PCB <= 1.2mm is recommended)
• M2 heatset inserts - 4mm length, 3.2mm diameter for resin case or 3.5mm for Nylon/PLA
• push buttons - 10mm height for KS, 15mm for MX
• push button caps - 3.1 inner diameter
