First-party packages 📦 from atopile

This is a monorepo for all the loose packages published by atopile.

Project-specific packages are published from their own repos.

Development

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

Building Packages

To build all packages in the repository, use the build-all.sh script:

bash
# Build all packages
./build-all.sh

# Build all packages with specific flags (e.g., --frozen)
./build-all.sh --frozen

The script will attempt to build each package and provide a summary report of successes and failures.

Questions

What parts does the Rightangle-4 use?

20 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 Rightangle-4 KiCad files?

From the atopile/packages repository on GitHub, at the commit this page was made from: the board is packages/saleae-header/layouts/rightangle-4/rightangle-4.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Rightangle-4 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).
