Questions
How big is the IFBoard PCB?
It measures 40 × 25 mm and has 2 copper layers, 1.6 mm thick.
What parts does the IFBoard use?
36 parts, built around the LT6202CS8#PBF and AD8031ARTZ-REEL7. 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 IFBoard KiCad files?
From the ear0/ECE445_Team18 repository on GitHub, at the commit this page was made from: the board is hardware/pcb/IFBoard/IFBoard.kicad_pcb and its schematic hardware/pcb/IFBoard/IFBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the IFBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask ear0 before reusing the design.
