Questions
How big is the Uefi basic v1 PCB?
It measures 35 × 32.7 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Uefi basic v1 use?
74 parts, built around the LM321, OPA340NA, 74HC4851D and K26. 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 Uefi basic v1 KiCad files?
From the Churrosoft/OpenEFI-PCB_next repository on GitHub, at the commit this page was made from: the board is sensors/uefi_basic_v1/uefi_basic_v1.kicad_pcb and its schematic mainboard_uEFI/connector.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Uefi basic v1 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).
