Conventions
Package name restrictions:
-
kebab-case
-
starts with a letter
-
"[a-z][0-9-]+"
-
project directories MUST have the same name as the package
-
drivers for ICs SHOULD be in the format "-x?". eg ti-bq240x
- there should be a single "x" on the end if there are multiple variants of the same part family
- the manufacturer stub should be omitted if the they already do this for ths
-
modules and files should be named like "x?"
- "x" is optional if there is only one variant of the part family
- omit the manufacturer stub from the filename
-
components should be named like ""
-
build names should be:
- "ref-" for reference designs
- "test-" for test builds
- "example-" for example builds
- if only one IC/set of builds exist in a package, the name can be omitted

Questions
What parts does the Usage use?
9 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 Usage KiCad files?
From the atopile/packages repository on GitHub, at the commit this page was made from: the board is packages/st-lsm9ds1/layouts/usage/usage.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usage design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
