Proteus PCB

Proteus67 - Ortholinear mechanical keyboard

• 67 Key ortholinear design, inspiration taken from the split design of the Sofle/Lily58 and Planck

• 33 keys per hand

• 1 Rotary encoder in the middle (Green)

• Additional column positioned each side down the centre. (Orange)

• Single microcontroller design while retaining characteristics of a split layout

• 130mm finger spacing while hands are at home positions (F/J keys) in a QWERTY layout. (Blue)

• As there is no base plate by default, I've provided PCB files and laser cutting stencils which can be fabricated, if mounting on a plate you'll also require M2 standoff's and screws.

• There is also a 3D printed case STL which fits the keyboard with the PCB resting on printed supports within the case, mounting screws not required.

• Firmware now part of QMK official repo: https://github.com/qmk/qmk_firmware

  • If you need any assistance with building your firmware then please reach out.

• Fully supported with VIA when flashed with VIA keymap: https://usevia.app/

Assembly Guide

• I have provided additional images here which show assembly.
• Place both stabalizers into the top plate
• Insert all switches into the top plate and put to the side
• Diode installation: Must be on the rear of the board due to lack of clearance from stabalisers.
  • SMD mounting: Use smaller diode points marked below, ensure diodes are facing the correct orientation
  • Through-Hole mounting: Use the wider spacing through-holes, ensuring diodes are facing the correct orientation.
    • Snip off excess on top side.
• Reset switch: snip off legs before positioning on board.
  • Place switch on top side of PCB and solder from underside
• Microcontroller needs to be positioned with the top of the board facing upwards (Test controller beforehand and flash firmware using QMK)
• Place the rotary encoder on the top side and solder all points ensuring it stays flush to the board.
• Press down the top plate with switches and stabalisers down on the middle plate ensuring that all the switches sit flush against the middle plate.
• Turn board over and proceed to solder switches to the board
• Connect USB to keyboard and check all keys are functional, this is assuming you've already flashed the firmware to the MCU.
