CocktailBerry Hardware is the official hardware repository for the CocktailBerry project. It holds the machine designs (FreeCAD sources) and custom PCB(A)s (KiCad projects) you need to build your own CocktailBerry machine.
Build guides, parts lists, specifications, and downloadable fabrication files live in the Hardware Documentation. For the software, setup, and configuration, see the main CocktailBerry project and the Software Documentation.

Designs
Sources live in this repo; fabrication files (Gerbers/BOM/CPL for boards, STEP/STL for machines) are generated from them by the build pipeline. Full specs, parts, and downloads are on the Hardware Documentation.

Contributing / How to Help
Contributions are very welcome - a new machine design, an improved model, or a PCB layout. Open an issue or pull request.
Please submit source files only:
- PCBs: the KiCad project (
*.kicad_sch,*.kicad_pcb, and any local symbols/footprints) - Machines: the FreeCAD sources (
*.FCStd)
Do not commit generated fabrication artifacts (Gerbers, drill, CPL, STL, STEP) - those are
built from the sources by the pipeline (see pcb/README.md and
cad/README.md). See the main project's
Contributing Guidelines
for general rules.

Questions
How big is the Cbb i2c PCB?
It measures 67.1 × 57.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cbb i2c use?
85 parts, built around the MCP23017-E/SS, KT-0603R, 0603WAF1000 and 0603WAF1002. 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 Cbb i2c KiCad files?
From the AndreWohnsland/CocktailBerry-Hardware repository on GitHub, at the commit this page was made from: the board is pcb/cbb-i2c/cbb-i2c.kicad_pcb and its schematic pcb/cbb-gpio/mk1-cbb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cbb i2c design in my own project?
Its repository states no licence, so its author keeps all rights: ask AndreWohnsland before reusing the design.
