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