Questions

How big is the Transformer PCB?

It measures 57 × 77 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Transformer use?

7 parts. 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 Transformer KiCad files?

From the MagGenix/AMF-Generator repository on GitHub, at the commit this page was made from: the board is Transformer/Transformer.kicad_pcb and its schematic AMF-Generator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Transformer design in my own project?

Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
