Questions
How big is the PiFA 8xy PCB?
It measures 87 × 56 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PiFA 8xy use?
69 parts, built around the 74HCT541D, DS1307+, TBD62083APG and FOD814A300W. 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 PiFA 8xy KiCad files?
From the trihome/RasPi_PiFA repository on GitHub, at the commit this page was made from: the board is PiFA_8xy/PiFA_8xy.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the PiFA 8xy design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
