Questions

How big is the Power Supplies PCB?

It measures 327.6 × 186.9 mm and has 4 copper layers, 1.59 mm thick.

What parts does the Power Supplies use?

261 parts, built around the SSM2019BRNZ, OPA2134UA, NE5532AD and TPA6110A2DGN. 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 Power Supplies KiCad files?

From the joshieyu/DigitalAudioMixer repository on GitHub, at the commit this page was made from: the board is Power_Supplies_MAIN/Power_Supplies.kicad_pcb and its schematic Audio_Board_AD_Breakout/1.8V_PSU_sch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Power Supplies design in my own project?

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