Questions
How big is the Cjb PCB?
It measures 99.8 × 90.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cjb use?
123 parts, built around the FT230XS-R, PAM8406DR, LM1117DT-3.3 and PCM5100APW. 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 Cjb KiCad files?
From the 0x007E/cjb repository on GitHub, at the commit this page was made from: the board is pcb/CJB.kicad_pcb and its schematic pcb/CJB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cjb design in my own project?
Its repository states no licence, so its author keeps all rights: ask 0x007E before reusing the design.
