Questions
How big is the Cbi PCB?
It measures 43.8 × 31.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cbi use?
87 parts, built around the CNY17-4, BAT43, MMBFJ113 and AO3416A. 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 Cbi KiCad files?
From the 0x007E/cbi repository on GitHub, at the commit this page was made from: the board is pcb/CBI.kicad_pcb and its schematic pcb/CBI.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cbi design in my own project?
Its repository states no licence, so its author keeps all rights: ask 0x007E before reusing the design.
