Questions
How big is the Core board PCB?
It measures 375.9 × 152.4 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Core board use?
138 parts, built around the TPS54332DDAR, LD1117V33, PCIE-LP-01-01-F-DV-A-TR and B340. 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 Core board KiCad files?
From the calstar/le2-avionics repository on GitHub, at the commit this page was made from: the board is core_board/core_board.kicad_pcb and its schematic core_board/buck_converter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Core board design in my own project?
Its repository states no licence, so its author keeps all rights: ask calstar before reusing the design.
