Questions

How big is the Framework ExpansionBay IO Module PCB?

It measures 118.7 × 72.5 mm and has 4 copper layers, 1.02 mm thick.

What parts does the Framework ExpansionBay IO Module use?

90 parts, built around the FUSB303BTMX, FUSB340TMX, UPD720201K8-701-BAC-A and 24LC32A-I/SN. 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 Framework ExpansionBay IO Module KiCad files?

From the XPModder/Framework-ExpansionBay repository on GitHub, at the commit this page was made from: the board is ExpansionBay ExtensionCard Module/Framework-ExpansionBay-IO-Module/Framework-ExpansionBay-IO-Module.kicad_pcb and its schematic ExpansionBay ExtensionCard Module/Framework-ExpansionBay-IO-Module/Framework-ExpansionBay-IO-Module.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Framework ExpansionBay IO Module design in my own project?

Its repository states no licence, so its author keeps all rights: ask XPModder before reusing the design.
