Viterbi Keyboard - 5x7 70% Split Ortholinear

Viterbi Keyboard - 5x7 70% Split Ortholinear

Regular price $19.99 Sale

5x7 70% Split Ortholinear keyboard, more keys for more fun!

Item Notes

The PCB Kit includes the following:

  • 2 Viterbi PCBs
  • 2 Push buttons for reset
  • 2 4.7kΩ resistors for I2C
  • 2 TRRS jacks (no need to buy separately)
  • 70 1N4148 diodes

Layout

Each half of the board is a 5x7 matrix, but there is the option to have a 2u key in the lower left and right corners in place of 2 1u keys. The spot for the 2u has holes for Cherry PCB mounted stabilizers.

In place of the 5x1u keys on the bottom row, 4x1.25u keys can be used instead.

There's also a spot on the PCB for a pushbutton switch to reset the Pro Micro for flashing. No more taking a wire/tweezers/screwdriver to jump the Reset and GND pins!

The Name

As usual with these split ortho boards, we had to christen the board with a term from bakingpy's past. He used to implement the Viterbi Algorithm a number of times to take 2N received bits from a communications signal and figure out the original N bits it was encoded from. So here, signals from 2 board halves, decoded into one board, it's like this thing named itself.

Firmware

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

Case

Here's 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 identical to that of the Nyquist except for the additional column, so you can use this guide.
