Nyquist/Levinson Rev. 4 PCB Kit - 60%/40% Split Ortholinear Keyboard


The Nyquist is a 60% split ortholinear keyboard, that can also be converted easily to a 40% split ortholinear by breaking off the bottom row (by hand). Now featuring hotswap sockets, so just pop in your switches, and you are good to go!

Improvements with Rev. 4 PCBs: New features include per-key RGB, hotswap sockets, and a more powerful on-board microcontroller!!


  • MX Hotswap sockets
  • Option for rotary encoders at top-left and top-right corners (non-hotswappable)
    • Bottom row can optionally be broken off to convert the board into a Levinson layout (4x12 split)
    • Per-key RGB LEDs and underglow LEDs pre-installed
    • USB-C port
    • Compatible with MX-style switches only
    • QMK compatible, pre-flashed with VIA support for easy remapping of keys
    • The right half PCB has an optional 4-pin JST port add-on that can be used to reflash the PCB if you decide to break off the main USB-C port (for compatibility with SP50 case). Use JST-SH cable with Micro-USB breakout board or USB-C breakout board if doing this.
