Viterbi Keyboard - 5x7 70% Split Ortholinear PCB Kit

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.

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!

• 2 Viterbi PCBs
• 2 Push buttons for reset
• 2 4.7kΩ resistors for I2C
• 2 TRRS jacks
• 70 1N4148 diodes
• 2 MOSFETs and 2 4.7kΩ resistors for LED support

Viterbi Build Guide

This keyboard uses the popular open-source QMK Firmware with VIA enabled out of the box to allow you to remap all the keys just the way you want them.

Plug your keyboard in, open up the VIA app, and easily change what each key does to get the most out of your keyboard with your customizations! More info on what you can do here: VIA Usage Guide

• 2 Arduino Pro Micro or Elite-C (you can mix and match)
• Switches - Alps or MX-compatible
• Case/Plates
• TRRS cable
• Micro USB cable
• Optional - 2u PCB mount MX stabilizer if using 2u keys

Here's the case files for the Viterbi: Viterbi Case on GitHub

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.

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