Questions
How big is the BFS9000 PCB?
It measures 252.4 × 149.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BFS9000 use?
237 parts, built around the MBR120VLSF and SI2301CDS. 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 BFS9000 KiCad files?
From the jguillen-lab/BFS9000 repository on GitHub, at the commit this page was made from: the board is hardware/BFS9000/BFS9000.kicad_pcb and its schematic hardware/BFS9000/Addressable RGB LEDs.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BFS9000 design in my own project?
Its repository states no licence, so its author keeps all rights: ask jguillen-lab before reusing the design.
