Questions
How big is the PowerCube PCB?
It measures 200 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PowerCube use?
50 parts, built around the 1N4148W and SS34. 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 PowerCube KiCad files?
From the akkdong/PowerCube repository on GitHub, at the commit this page was made from: the board is hw/schematic/power-cube.kicad_pcb and its schematic hw/schematic/power-cube.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PowerCube design in my own project?
Its repository states no licence, so its author keeps all rights: ask akkdong before reusing the design.
