Questions

How big is the Expansion Card Retrofit PCB?

It measures 24 × 27.3 mm and has 4 copper layers, 0.8 mm thick.

What parts does the Expansion Card Retrofit use?

44 parts, built around the GD25D05CTIGR, MS2130, USBLC6-2P6 and R1M. 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 Retrofit KiCad files?

From the TheUnproductive/FrameworkHDMICaptureCard repository on GitHub, at the commit this page was made from: the board is ExpansionCards/Electrical/KiCad_templates/Expansion_Card_Retrofit/Expansion_Card_Retrofit.kicad_pcb and its schematic ExpansionCards/Electrical/KiCad_templates/Expansion_Card_Retrofit/Expansion_Card_Retrofit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Expansion Card Retrofit design in my own project?

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