Questions
How big is the Small rack PCB?
It measures 145 × 127 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Small rack use?
188 parts, built around the R-535.0PA, SN65LVDM176DGK, CY7C65631-56LTXC and MAX1685EEE+. 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 Small rack KiCad files?
From the easy-phi/main repository on GitHub, at the commit this page was made from: the board is Rack/Current Version/github/Kicad/small_rack.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Small rack design in my own project?
Its repository states no licence, so its author keeps all rights: ask easy-phi before reusing the design.
