Questions
How big is the Power board PCB?
It measures 48 × 20 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Power board use?
15 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 Power board KiCad files?
From the Barbatronic/modular-soldering-workbench repository on GitHub, at the commit this page was made from: the board is ECAD/power-board/power-board.kicad_pcb and its schematic ECAD/power-board/power-board.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 Barbatronic before reusing the design.
