Questions
How big is the Quartz58 PCB?
It measures 334.4 × 142.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Quartz58 use?
140 parts, built around the TPS65-201A-S. 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 Quartz58 KiCad files?
From the timwhat/Quartz58 repository on GitHub, at the commit this page was made from: the board is PCB/quartz58.kicad_pcb and its schematic PCB/quartz58.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Quartz58 design in my own project?
Its repository states no licence, so its author keeps all rights: ask timwhat before reusing the design.
