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?

13 parts, built around the ESP32-C6-WROOM-1-N8 and 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 KaptenIT/Framework-ESP32-Module repository on GitHub, at the commit this page was made from: the board is Expansion_Card.kicad_pcb and its schematic Expansion_Card.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

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

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