Overview
Giraffe36 pcb routed is an open-source printed circuit board by sboysel, from the sboysel/giraffe36 repository on GitHub, published under the CC-BY-4.0 licence. It is a 2-layer board of 130.1 × 118.9 mm with 21 parts on 34 nets, routed with 186 tracks and 0 vias.
Its parts include 18 switches and 1 IC. It belongs with the keyboards and input boards and the RP2040 boards of this library.
README
README.mdgiraffe36
A 36 key split keyboard with "long-necked" thumb clusters. Wired, powered by Raspberry Pi Picos, diodeless. Inspirations include Ferris Sweep / sweep36, draculad, samoklava, piantor.
Status: v0.0.1 / e54525c prototypes have been tested and are functional. See Tags.
Goals
- simplicity
- declarative design (ergogen and specifically, my fork)
- 5x3+3 wired split
- soldered MX to build plateless
- diodeless
- lowered thumb cluster comfortable to my hands
- to learn PCB design!
Build
BOM
- 2x PCB (they are reversible, fabricated by JLCPCB)
- 2x Raspberry Pi Pico (I used WeAct Studio Pi Picos)
- 2x TRRS PJ-320A jack (4 pins)
- 36x MX switches
Be sure to use the main branch. Gerbers can be found in output/pcbs/routed/. Archives of the routed PCB and gerbers are located in output/pcbs/routed/backups. Firmware (KMK) can be found in firmware/kmk/.
Development
Setup
git clone git@github.com:sboysel/giraffe36.git
python -m venv --system-site-packages ~/.venv/giraffe36
cd giraffe36
npm install
pip install -r requirements.txt
makeThe main branch contains versions of the board that have been tested and are confirmed to be functional. The dev branch contains the latest progress on the next iteration.

Questions
How big is the Giraffe36 pcb routed PCB?
It measures 130.1 × 118.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Giraffe36 pcb routed use?
21 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 Giraffe36 pcb routed KiCad files?
From the sboysel/giraffe36 repository on GitHub, at the commit this page was made from: the board is output/pcbs/routed/giraffe36_pcb_routed.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Giraffe36 pcb routed design in my own project?
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
