Questions
How big is the Cbp PCB?
It measures 43.8 × 31.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cbp use?
34 parts, built around the LM2575-12BU, L7805, LM1117DT-3.3 and B360A. 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 Cbp KiCad files?
From the 0x007E/cbp repository on GitHub, at the commit this page was made from: the board is pcb/CBP.kicad_pcb and its schematic pcb/CBP.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cbp design in my own project?
Its repository states no licence, so its author keeps all rights: ask 0x007E before reusing the design.
