Questions
How big is the PC8477 PCB?
It measures 101.8 × 57 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PC8477 use?
39 parts. 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 PC8477 KiCad files?
From the climatex/MegaFDC repository on GitHub, at the commit this page was made from: the board is Boards/PC8477/PC8477.kicad_pcb and its schematic Boards/DP8473/DP8473_v11.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PC8477 design in my own project?
Its repository states no licence, so its author keeps all rights: ask climatex before reusing the design.
