Questions
How big is the Elf fp PCB?
It measures 89 × 112 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Elf fp use?
34 parts, built around the 74HC00D and TB003-500-P02BE. 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 Elf fp KiCad files?
From the arhefner/elf_mc_fp repository on GitHub, at the commit this page was made from: the board is Kicad/elf_fp/elf_fp.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Elf fp 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).
