Questions
How big is the Bbbmini PCB?
It measures 86.4 × 54.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bbbmini use?
37 parts, built around the MCP2562-H/P. 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 Bbbmini KiCad files?
From the mirkix/BBBMINI-PCB repository on GitHub, at the commit this page was made from: the board is kicad/bbbmini/bbbmini.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bbbmini design in my own project?
Its repository states no licence, so its author keeps all rights: ask mirkix before reusing the design.
