Questions
How big is the C64PSUv3 PCB?
It measures 66.3 × 34.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the C64PSUv3 use?
37 parts, built around the L298N and BZT52B12. 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 C64PSUv3 KiCad files?
From the FabioNMI/C64PSU repository on GitHub, at the commit this page was made from: the board is C64PSUv3/C64PSUv3.kicad_pcb and its schematic C64PSUv3/C64PSUv3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the C64PSUv3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask FabioNMI before reusing the design.
