Questions
How big is the Quartz PCB?
It measures 254 × 130 mm and has 6 copper layers, 1.6 mm thick.
What parts does the Quartz use?
1,244 parts, built around the INA851RGTR, AD7768BSTZ, ADA4841-1YRJZ-R2 and AMC7823IRTAT. 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 Quartz KiCad files?
From the osprey-dcs/Quartz repository on GitHub, at the commit this page was made from: the board is Quartz.kicad_pcb and its schematic ADC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Quartz design in my own project?
Its repository states no licence, so its author keeps all rights: ask osprey-dcs before reusing the design.
