PCB and keymap files for the SLZ40, a 40s style keyboard with numbers for Zhuyin input.
The PCB requires a Pro Micro (or comparable) controller as well as 58 diodes, 58 MX style switches
The sandwich case takes M2 screws and standoffs.
You can find the key caps required in the following layout.
| cap size | number | R1 | R2 | R3 | R4 | R5 |
|---|---|---|---|---|---|---|
| 1u | 47 | 11 | 13 | 10 | 10 | 3 |
| 1.25u | 6 | 0 | 0 | 1 | 1 | 4 |
| 1.5u | 1 | 0 | 0 | 0 | 0 | 1 |
| 1.75u | 4 | 0 | 0 | 1 | 1 | 2 |
QMK toolbox is required to flash the layout
The default keymap can be found in the keymap folder.
A hex of the default layout can be found here to make sure the keyboard is working.
-- Update 6/24/2024 Added firmware for Via/Vial compatability.

Questions
How big is the SithZhuyin40 PCB?
It measures 247.7 × 95.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SithZhuyin40 use?
117 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 SithZhuyin40 KiCad files?
From the sithlord121/slz40 repository on GitHub, at the commit this page was made from: the board is PCB-files/PCB/SithZhuyin40.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the SithZhuyin40 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).
