Questions

How big is the SwitchingBoard PCB?

It measures 100 × 74.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the SwitchingBoard use?

53 parts, built around the BTB16-800CW and STTH110. 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 SwitchingBoard KiCad files?

From the HMGrunthos/InrushTimer repository on GitHub, at the commit this page was made from: the board is SwitchingBoardKiCad/SwitchingBoard.kicad_pcb and its schematic SwitchingBoardKiCad/SwitchingBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the SwitchingBoard design in my own project?

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