Questions
How big is the Capstone pcb PCB?
It measures 60.2 × 43.6 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Capstone pcb use?
48 parts, built around the NRF52840-QIAA-R, MAX30102EFD+T, BSS138 and AMS1117-1.8. 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 pcb KiCad files?
From the austish/NuvoMotionPCB repository on GitHub, at the commit this page was made from: the board is capstone_pcb.kicad_pcb and its schematic capstone_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Capstone pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask austish before reusing the design.
