Questions
How big is the Cbb PCB?
It measures 43.8 × 31.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cbb use?
33 parts, built around the ATTINY1606-SF and ATA6563-GAQW1. 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 Cbb KiCad files?
From the 0x007E/cbb repository on GitHub, at the commit this page was made from: the board is pcb/CBB.kicad_pcb and its schematic pcb/CBB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cbb design in my own project?
Its repository states no licence, so its author keeps all rights: ask 0x007E before reusing the design.
