Questions
How big is the GB LIVE32 PCB?
It measures 51.4 × 61 mm and has 4 copper layers, 1 mm thick.
What parts does the GB LIVE32 use?
61 parts, built around the 74LVC245APW, 74LVC1G07, 74LVC1G32Z and 74LVC8T245PW. 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 GB LIVE32 KiCad files?
From the Gekkio/gb-hardware repository on GitHub, at the commit this page was made from: the board is GB-LIVE32/GB-LIVE32.kicad_pcb and its schematic GB-BENCH-G1/GB-BENCH-G1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the GB LIVE32 design in my own project?
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
