Questions

How big is the Power board PCB?

It measures 187 × 352.1 mm and has 4 copper layers, 1.67 mm thick.

What parts does the Power board use?

346 parts, built around the LMV393, 74HC595, NMUX1308PWJ and BAT54S. 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 board KiCad files?

From the FilipNorlin/Split_Rail_Power_supply repository on GitHub, at the commit this page was made from: the board is Rev_1/ECAD/power_board/power_board.kicad_pcb and its schematic Rev_1/ECAD/power_board/ac_input_filter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

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

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