Published November 16, 2022
Creators! Feel free to tip me off about your keyboard related projects to bring them to 100K readers.

Litl is an easy to build 40% keyboard using only through-hole components.

Just like its big brother, the Lagom, it uses a separate daughterboard for microcontrollers with Pro Micro footprint.


  • Only through hole components for easy soldering
  • Supports Pro Micro, Elite C, Nice!Nano or equivalent development boadrds with compatible footprint. (So micro USB, USB-C or Bluetooth are all options!)
  • 1 or 2 rotary encoders
  • OLED screen (though only 1 rotary encoder is possible if using OLED)
  • Multiple layout options including split space (2.25u + 1u + 2.75u), split left shift (1.25u + 1u), split enter (1u + 1.25u) and stepped capslock
  • Open and visible components (in the style of Plaid, Romac etc.)
  • Simple and flexible case options
