Questions
How big is the Gbczero PCB?
It measures 71.4 × 128 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Gbczero use?
78 parts, built around the PAM8302AADCR, TPS61030PWP, 74HC00D and 74HC04D. 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 Gbczero KiCad files?
From the hahhen/gbczero repository on GitHub, at the commit this page was made from: the board is gbczero/gbczero.kicad_pcb and its schematic gbczero/gbczero.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Gbczero design in my own project?
Its repository states no licence, so its author keeps all rights: ask hahhen before reusing the design.
