Questions
How big is the Bbar3 PCB?
It measures 20 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bbar3 use?
4 parts. 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 Bbar3 KiCad files?
From the na103/bbar3 repository on GitHub, at the commit this page was made from: the board is Kicad/RC/RC.kicad_pcb and its schematic Kicad/BBARIII/BBARIII.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bbar3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask na103 before reusing the design.
