Questions
How big is the BC832A PCB?
It measures 38.5 × 17 mm and has 4 copper layers, 1.6 mm thick.
What parts does the BC832A use?
32 parts, built around the AP2112K-3.3 and IP4234CZ6. 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 BC832A KiCad files?
From the tomfleet/BC832A repository on GitHub, at the commit this page was made from: the board is BC832A.kicad_pcb and its schematic BC832A.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BC832A design in my own project?
Its repository states no licence, so its author keeps all rights: ask tomfleet before reusing the design.
