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

$69.99 Sale Save

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.
  • Comes with left half PCB and right half PCB
  • RP2040 MCU integrated on-board
  • Per-key RGB LEDs for each switch
  • 8 RGB underglow LEDs on each half

The default keymapping that the board is pre-programmed with can be found here: Default Keymaps

Easy to Put Together Nyquist

This keyboard is the most comfortable keyboard I own. This is easily my favorite keyboard to type on, because of the key placements. As someone with a handicap that affects their typing, this keyboard makes me feel like I can type like normal again. Just snap on the switches with the case, and you are good to go. I had to spend some time programming the board, but that was part of the fun. This way, I could learn what layouts work best for me and where my fingers go naturally, now that I am not constrained to the traditional keyboard. I put some silent linear on this bad boy, and the silence in which I type has been the best experience. You can put clicky switches on it, if you really want. You will get a very satisfyingly isolated click per keystroke.

Before this keyboard, I loved typing my ZSA Ergodox EZ. Even with silent switches, the acoustics of the Ergodox case are very loud and jarring, very annoying. The Nyquist easily beats it by a mile.

I have had an older Nyquist Rev. 2 board that requires soldering for years. I had always told myself I was going to learn to solder to make my keyboard, but I never had the time. I built this keyboard in about two hours. It's very easy to program, too, once you figure out how you would like to type.

Went with 40% Levinson. Breaking the PCB made me so nervous!

Easy to put together. Very easy to adjust to the layout. Love how it looks.

Great Series

It seems like the iris gets all the love for some reason, but I truly think this is the best practical keyboard.

I've been using this keyboard for many generations at this point, back when you used to have to soldier everything yourself.

I want to make another low profile version, like this one: https://www.reddit.com/r/olkb/comments/vopv9m/keebio_nyquist_with_custom_laser_cut_bottom_plate/.
