Questions

How big is the Doorbell pcb v2 PCB?

It measures 50 × 75 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Doorbell pcb v2 use?

25 parts, built around the B5819 and DF06S. 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 Doorbell pcb v2 KiCad files?

From the paulc/c3zero-doorbell repository on GitHub, at the commit this page was made from: the board is pcb/doorbell_pcb_v2/doorbell_pcb_v2/doorbell_pcb_v2.kicad_pcb and its schematic pcb/doorbell_pcb/doorbell_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Doorbell pcb v2 design in my own project?

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