Dashie Keys

DIY Work in progress of my own keyboard using a Teensy 2.0++ and Cherry MX keys.

Oops

The schematics does have row1 to row8 but in fact the PCB is, from top to bottom: row8, row1 … row7. The schematics haven’t been updated for this change, which have been done while routing the board, the bottom row was put on the top for a better layout arrangement, sorry. The keyboard-layout json and builder reflects properly this change.

PD6 does have the builtin LED, causing some issues. Cut track between D6 and the switch pin and connect that pin to E0. E0 is pin number 11 from the right when you have the side with keys in front of you. See docs/track_fix.jpg for visual.

PCB Revisions

V1

See tag v1 for this revision.

This is the first one I made, some issues, but without too much impact if you are careful:

  • D48 is close to MK5 and may touch
  • lot of vias for ground plane stitching are very close to diodes or plated holes
  • D_1206 from KiCad libraries are made for reflow soldering, a bit tricky by hand, but it can be done slowly and carefuly

V2

This is the state of this current repository.

This PCB revision will fixes all points reported in the V1

Keys

  • Total : 92 keys
    • A-Z, 1-9, ,./\ etc. : 47
    • Modifiers (ctrl, start, altLR, shiftLR, tab, backspace, del, esc) : 11
    • Enter : 1
    • Space : 1
    • Navigation (<>V^, home, end, pg up down) : 8
    • Fx : 12
    • Special keys : 12

From my tastes:

  • clear : 60
    • normals, space, Fx
  • brown : 20
    • modifiers, navigation, enter
  • grey : 12
    • specials

You can choose differents feelings for the keys, you only need “PCB Mount” ones.

Firmware

It use QMK firmware

  git clone https://github.com/qmk/qmk_firmware/
  cd qmk_firmware
  make git-submodule
  cp -r ~/where/is/dashie-keys/firmware/dashie_keys keyboards/
  make dashie_keys:default

Then use any Teensy flasher to flash dashie_keys_default.hex.

Made With

  • KiCAD EDA
    • Version 5.x only, or nightly until 5.x is released. Format isn’t compatible with KiCAD 4.x.
