Questions
How big is the Detonator PCB?
It measures 55.2 × 78.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Detonator use?
13 parts, built around the IRF540N. 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 Detonator KiCad files?
From the hspeiser/rocket-development repository on GitHub, at the commit this page was made from: the board is detonator/detonator/detonator.kicad_pcb and its schematic detonator/detonator/detonator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Detonator design in my own project?
Its repository states no licence, so its author keeps all rights: ask hspeiser before reusing the design.
