Questions
How big is the FanFDD PCB?
It measures 88 × 88 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FanFDD use?
57 parts, built around the 74AHC1G125GW and OPA344PA. 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 FanFDD KiCad files?
From the idlehandsdev/fanFDD repository on GitHub, at the commit this page was made from: the board is PCB/fanfdd.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the FanFDD design in my own project?
Its repository states no licence, so its author keeps all rights: ask idlehandsdev before reusing the design.
