Questions
How big is the ReactorConsole PCB?
It measures 157.5 × 108.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ReactorConsole use?
154 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 ReactorConsole KiCad files?
From the code2344/reactor repository on GitHub, at the commit this page was made from: the board is ReactorConsole PCB/ReactorConsole.kicad_pcb and its schematic ReactorConsole PCB/ReactorConsole.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ReactorConsole design in my own project?
Its repository states no licence, so its author keeps all rights: ask code2344 before reusing the design.
