Questions
How big is the Mini adapter PCB?
It measures 50 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mini adapter use?
18 parts, built around the RJ45. 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 Mini adapter KiCad files?
From the GBert/misc repository on GitHub, at the commit this page was made from: the board is BPI-AddOn/mini-adapter/mini-adapter.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mini adapter design in my own project?
Its repository states no licence, so its author keeps all rights: ask GBert before reusing the design.
