Overview
Keyboard is an open-source printed circuit board by DiScarlet, from the DiScarlet/Keyboard repository on GitHub. It is a 2-layer board of 264.8 × 109.2 mm with 108 parts on 79 nets, routed with 376 tracks and 81 vias.
Its parts include 52 diodes and 52 switches. It belongs with the keyboards and input boards and the ESP32 boards of this library.
README
README.mdDuck Keyboard
Why are the Space and Tab keys so big? Completely unnecessary.
We are not accountants. Why should some keys get more space than others?
We demand equality. Equality and ducks.
52 keys. Zero keycap inequality.
Ducks, palm trees, and pure summer vibes. Tactile. Compact.
And yes — it quacks when you press it.
Built for minimalists who still want to have fun.
Features
- 52-key compact layout
- Uniform key sizes with no oversized Space or Tab keys
- Tactile typing experience
- Custom duck-themed design
- Compact footprint for minimalist setups
- Integrated sound effects: every keypress quacks
Design Philosophy
Most keyboards dedicate excessive space to a handful of keys while the rest compete for room.
The Duck Keyboard rejects keycap inequality. Every key deserves equal treatment.
Zine
CAD Model and Case
The keyboard case uses Gasket Mounting and was designed to complement the compact layout while maintaining a clean, minimalist appearance.

Electronics
Schematic
The keyboard electronics are based on a custom schematic designed usinf KiCAD.
PCB
The custom PCB uses ESP32 Feather.
3D PCB View
Assembly Instructios
- Flash the ESP32 Feather with the firmware.
- Solder the hot-swap sockets and the ESP32 Feather to the PCB.
- Install the switches into the hot-swap sockets.
- 3D print the top case, bottom case, and keycaps.
- Place the PCB assembly into the case and secure it using M2 screws.
- Install the keycaps onto the switches.
- 3D print the decorative duck and palm tree elements.
- Attach the decorations to the designated area of the top case using instant glue (cyanoacrylate).
- (Optional) Print the angle-of-attack wedge to tilt the keyboard toward the user for a more comfortable typing position.

Questions
How big is the Keyboard PCB?
It measures 264.8 × 109.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keyboard use?
108 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 Keyboard KiCad files?
From the DiScarlet/Keyboard repository on GitHub, at the commit this page was made from: the board is Hardware/keyboard.kicad_pcb and its schematic Hardware/keyboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keyboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask DiScarlet before reusing the design.
