Content
The repo currently contains KiCAD source files for the main board, interface board and a tiny sensor head. It also includes all accompanying files, such as BOM.
Building
The supplied makefile uses KiKit to automatically generate all output gerber files for JLCPCB.
Just run make in the top level directory to create all output gerbers and zip them in the ./gerber/ folder.
3D models, schematic symbols, footprints
This project relies on LoaDy KiCAD Libs for some footprints and the 3D models in the 3D preview on PCBNew
License
The Main Board and Interface Board are licensed under CERN-OHL-W v2.
The MLX90393 sensor head is not licensed at all.

Questions
How big is the Interface board PCB?
It measures 58 × 43 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Interface board use?
45 parts, built around the PCA9600DP, SC18IS602B and PESD12VS2UT. 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 Interface board KiCad files?
From the emlab-fi/cube_electronics repository on GitHub, at the commit this page was made from: the board is interface_board/kicad_project/interface_board.kicad_pcb and its schematic encoder_expansion_board/axis_input.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Interface board design in my own project?
Its repository states no licence, so its author keeps all rights: ask emlab-fi before reusing the design.
