Questions
How big is the Bonkpu PCB?
It measures 152.7 × 156.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bonkpu use?
3 parts, built around the 74LS245SC and 74LS173SC. 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 Bonkpu KiCad files?
From the Mike111177/bonkpu repository on GitHub, at the commit this page was made from: the board is schematic/bonkpu.kicad_pcb and its schematic schematic/Memory.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bonkpu design in my own project?
Its repository states no licence, so its author keeps all rights: ask Mike111177 before reusing the design.
