Questions
How big is the RouterCoreBaseRevA PCB?
It measures 65 × 52 mm and has 8 copper layers, 1.6 mm thick.
What parts does the RouterCoreBaseRevA use?
127 parts, built around the TCA9544APW, FDMC86139P, SEAF-20-05.0-L-10-2-A-K-TR and SMAJ54CA. 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 RouterCoreBaseRevA KiCad files?
From the botblox/RouterCoreCore-Baseboard-Designs repository on GitHub, at the commit this page was made from: the board is RouterCoreBaseRevA Design Files/RouterCoreBaseRevA.kicad_pcb and its schematic RouterCoreBaseRevA Design Files/Power.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RouterCoreBaseRevA design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
