A custom mechanical keyboard PCB designed in KiCad 8.
Structure
| Directory | Description |
|---|---|
/ (root) | Main v3 PCB — schematic and board layout. |
top-plate/ | Top plate PCB — used as the switch plate. |
Both are independent KiCad projects sharing the same design settings.
Dependencies
The project references an external footprint library configured in fp-lib-table:
- Lily58 — Lily58 keyboard footprints (
${KIPRJMOD}/../../Lily58/pcb/Lily58-footprint.pretty)
Open the project in KiCad 8.0 or later.

Questions
How big is the Dso 26 PCB?
It measures 139.1 × 118.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dso 26 use?
54 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 Dso 26 KiCad files?
From the codingdestro/dso_26 repository on GitHub, at the commit this page was made from: the board is pcb/dso_26/dso_26.kicad_pcb and its schematic pcb/dso_26/dso_26.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dso 26 design in my own project?
Its repository states no licence, so its author keeps all rights: ask codingdestro before reusing the design.
