Questions

How big is the Capstone v2 PCB?

It measures 14 × 20 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Capstone v2 use?

18 parts, built around the HSFPAR004A. 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 Capstone v2 KiCad files?

From the ndxw/InkSync repository on GitHub, at the commit this page was made from: the board is pcb/capstone_v2/capstone_v2.kicad_pcb and its schematic pcb/PCB_Capstone_prototype_1_optical_S/PCB_Capstone_prototype_1_optical_S.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Capstone v2 design in my own project?

Its repository states no licence, so its author keeps all rights: ask ndxw before reusing the design.
