Extension-board hardware includes independent Ccecil repositories pinned as Git submodules
and legacy board designs copied from this repository's master:extensions tree, all under
extension-boards/. Clone with --recurse-submodules to initialize the
Ccecil boards, or initialize them in an existing clone with
git submodule update --init --recursive. The legacy designs are ordinary tracked folders;
their source revisions and folder mappings are documented in
extension-boards/README.md.

Questions
How big is the Smoothiev2-prime PCB?
It measures 110 × 110 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Smoothiev2-prime use?
453 parts, built around the 74HCT541D, 74LCX07T, TMC2590-TA and TPD4E1U06DCKR. 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 Smoothiev2-prime KiCad files?
From the Smoothieware/Smoothieboard2 repository on GitHub, at the commit this page was made from: the board is V2_P12_Prime2590/smoothiev2-prime.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Smoothiev2-prime design in my own project?
Its repository states no licence, so its author keeps all rights: ask Smoothieware before reusing the design.
