Levinson Keyboard - 40% Split Ortholinear (Let's Split w/LED backlight) - PCB Kit

Regular price $19.99 $14.99 Sale

The Levinson is like the Let's Split but with LED backlight and 2u key support.

Item Notes

Note: PCB Kit no longer includes LED support components to reduce price, as not everyone used these. The MOSFET and resistors for the MOSFET are available separately via the LED Support Add-on Kit.

The PCB Kit includes the following:

  • 2 Levinson PCBs
  • 2 Push buttons for reset
  • 2 TRRS jacks
  • 48 1N4148 through-hole diodes
  • 2 4.7kΩ resistors for I2C

Layout

Each half of the board is a 4x6 matrix, but there is the option to have a 2u key in the innermost corners in place of 2 1u keys. The spot for the 2u has holes for Cherry PCB mounted stabilizers.

The Name

Continuing the theme of prominent people in signal processing and digital communications, the board is called the Levinson, after the Levinson-Durbin recursion algorithm. There also happens to be the Split Levinson recursion as well, which fits nicely into the world of split keyboards.

Firmware

The Levinson uses QMK for its firmware, and the code for it has been merged into the main codebase. You can find it here: QMK - Levinson directory.

Case

Cases and plates can be purchase here: Levinson/Let's Split Plates and Cases.

The case files for a sandwich-style case are still under development.

    The kerf setting was set to 0.15mm for use with Lasergist and Ponoko.

    Items needed for build

    The build guide is nearly identical to that of the Iris, so you can use this guide.
