Questions
How big is the Sinecore PCB?
It measures 33 × 15.2 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Sinecore use?
42 parts, built around the PMBT3904YS and PMBT3906YS. 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 Sinecore KiCad files?
From the versusentropy/sinecore repository on GitHub, at the commit this page was made from: the board is sinecore.kicad_pcb and its schematic sinecore.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sinecore design in my own project?
Its repository states no licence, so its author keeps all rights: ask versusentropy before reusing the design.
