Questions
How big is the BBB PCB?
It measures 39.9 × 22.7 mm and has 4 copper layers, 1.6 mm thick.
What parts does the BBB use?
36 parts, built around the STM32WBA50KGU6, LM393F-GE2, PPTC041LFBN-RC and 416F32022CKR. 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 BBB KiCad files?
From the SunDevilRocketry/Bluetooth-Breakout repository on GitHub, at the commit this page was made from: the board is Kicad Files/BBB/BBB.kicad_pcb and its schematic Kicad Files/BBB/BBB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BBB design in my own project?
Its repository states no licence, so its author keeps all rights: ask SunDevilRocketry before reusing the design.
