Cambridge University Spaceflight KiCAD Library

This repository coontains a collection of KiCAD symbols, footprints, and related files for use by Cambridge University Spaceflight.

Schematic Symbols

All symbols are contained in cusf-kicad.lib, although each individual symbol has its own .lib file which can be included separately. These files are built using scripts/compile_lib.py and kept up to date automatically.

Each part contains supplier order codes and manufacturer part numbers where possible and sensible. Parts are drawn as per the conventions in lib/README.md, based on the KiCAD project conventions.

Symbols for many ICs and other "black-box" parts are drawn automatically from .yaml files in the relevant directories, using the build-lib-ic.py script. Check some of these out for an example of the syntax etc.

Check the README in each library folder for details and notes on each part.

PCB Footprints

To use, add cusf.pretty to your project libraries, with nickname cusf recommended for compatibility with the schematic symbols.

Where possible footprints are based on the appropriate standards and follow the conventions in cusf.pretty/README.md, based on the KiCAD project conventions.

Many footprints for 2-terminal chip devices and 2- or 4- row SMD ICs are automatically generated using the build-mod-chip.py and build-mod-ic.py scripts, which contain the parametric specifications for all the footprints they should build. This includes things like 0402 resistors, DFN and QFP ICs, and similar sorts of footprints.

StickerBOM

StickerBOM is a script to convert your BOM into a PDF to print onto sticker labels, one label per BOM item. The labels have a drawing of the PCB to show you where that item goes, which makes hand assembly a lot nicer!

Scripts

See the README in the scripts folder for detailed information on each script.

The only requirement is PyYAML for some of the build scripts: sudo pip install pyyaml or similar.

Makefile

You can use the Makefile to:

• Rebuild all built-from-parameter files with make build
  • Just libraries with make build-libs
  • Just modules (footprints) with make build-mods
• Verify all built-from-parameter files are up-to-date with make build-verify
• Recompile all compiled outputs (the combined .lib and the .pro) with make compile
• Verify all compiled outputs are up-to-date with make compile-verify
• Verify both built and compiled outputs with make verify
• Check all files against rules with make check
  • Just libraries with make check-lib
  • Just modules with make check-mod

Additionally in scripts/ is pre-commit that stops any commits that do not pass make check and make build-verify, and post-commit that runs make compile-verify and if any compiled files are not up to date, recompiles them and commits the result. Copy these to .git/hooks for use.
