phalwol
Row staggered 60% keyboard with reversible PCB, inspired by Hatsukey70
Hatsuki means August in Japanese, and phalwol means August in Korean. This keyboard layout is an hommage to Hatsukey70, so I want to credit the original design by name.
This keyboard has additional Y/H/B keys which positioned between keyboards, and auxilary row at left outside. You may put the keycaps from numpad.
This keyboard has hotswap-only PCB.
phalwol can change layout to followings:
-
Split left shift, to ISO shaped one.(2.25u to 1.25u/1u)
-
Split right shift, to HHKB inspired shape.(2.75u to 1.75u/1u)
-
Split outside thumb keys(2u to 1u/1u)
-
Split backspace(2u to 1u/1u)
-
Can use stepped caps lock
Preparation
-
2x pro micro form factor dev board
-
2x phalwol PCB Boards, provided from the repo
-
1x printed case sets, 2 parts total, provided from the repo (for thicker case, use "buffed")
-
1x 1.5-1.6T keyboard plate sets, 2 parts total, provided from the repo
-
80x diodes, normally 1N4148
-
84x Kailh hotswap sockets (or compatibles)
-
16x M2x6 screws, flathead
-
2x PJ320A 1/8(3.5mm) TRRS connector (MJ-4PP-9 in other name)
-
2x 4x4x1.5mm surface mount tact switches (optional, for dev boards without reset button)
-
1x 1/8(3.5mm) TRRS cable
-
1-6x PCB Mounted 2u Keyboard Stabilizers, normally 6
-
73-78x MX Keyswitches, normally 73
-
8x 10mm bumpon stickers
-
A set of Keycaps, Full-size layout, ANSI preferred.
Differences between case variations
| Original | Buffed | Frame |
|---|---|---|
 |  |  |
(Frame case are lightest option for 3d print, but it is very brittle)
Build Guides and Miscellaneous
there's some notices before the build:
-
You may solder all hotswaps before soldering the dev board.
-
Assemble dev board with 2.5mm height pin headers on back side, assume that components side are faced up.
-
Jump every jumpers on front side.
Also take a look at the sibling, ilwol.

Questions
How big is the Phalwol PCB?
It measures 169.6 × 117 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Phalwol use?
114 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Phalwol KiCad files?
From the yuburoll/phalwol repository on GitHub, at the commit this page was made from: the board is kicad/phalwol.kicad_pcb and its schematic kicad/phalwol.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Phalwol design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
