Questions

How big is the A1200-psu PCB?

It measures 147 × 76 mm and has 2 copper layers, 1.6 mm thick.

What parts does the A1200-psu use?

64 parts, built around the TL431D, 1N4742A, 1N5230B and BYV26E. 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 A1200-psu KiCad files?

From the nbolton/amiga repository on GitHub, at the commit this page was made from: the board is hardware/a1200-psu/a1200-psu.kicad_pcb and its schematic hardware/a1200-psu/a1200-psu.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the A1200-psu design in my own project?

Its repository states no licence, so its author keeps all rights: ask nbolton before reusing the design.
