Reference designs and documentation to create Expansion Cards for the Framework Laptop. The Framework Laptop's Expansion Card system lets you choose exactly the ports you want and which side you want them on. We've built USB-C, USB-A, HDMI, DP, MicroSD, and Storage Expansion Cards, but there is an entire world of other interesting ways to extend the capabilities of a notebook. We're releasing CAD to make it easy for you to develop your own Expansion Cards.
Check out the Expansion Card section of the Framework Community for card ideas, support, or just to show off what you're working on: https://community.frame.work/c/expansion-cards/developer-program/90
Note that you should build and test development versions before committing a design based on this CAD to mass production.

Questions
How big is the Expansion Card PCB?
It measures 26 × 30 mm and has 2 copper layers, 0.8 mm thick.
What parts does the Expansion Card use?
11 parts, built around the AP2112K-3.3. 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 Expansion Card KiCad files?
From the FrameworkComputer/ExpansionCards repository on GitHub, at the commit this page was made from: the board is Electrical/KiCad_templates/Expansion_Card/Expansion_Card.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Expansion Card design in my own project?
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
