Questions
How big is the LC PCB?
It measures 71.6 × 60 mm and has 4 copper layers, 1.6 mm thick.
What parts does the LC use?
118 parts, built around the LAN8742A-CZ, AP2112K-3.3, USBLC6-2SC6 and SKRPANE010. 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 LC KiCad files?
From the npgo22/LC repository on GitHub, at the commit this page was made from: the board is LC.kicad_pcb and its schematic LC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LC design in my own project?
Its repository states no licence, so its author keeps all rights: ask npgo22 before reusing the design.
