Questions
How big is the Cbo PCB?
It measures 43.8 × 31.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cbo use?
82 parts, built around the ITS4140N, BAT43, AO3416A and MMBFJ113. 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 Cbo KiCad files?
From the 0x007E/cbo repository on GitHub, at the commit this page was made from: the board is pcb/CBO.kicad_pcb and its schematic pcb/CBO.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cbo design in my own project?
Its repository states no licence, so its author keeps all rights: ask 0x007E before reusing the design.
