Questions
How big is the BilgeAlarm PCB?
It measures 111.8 × 88.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BilgeAlarm use?
62 parts, built around the IRLZ44N. 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 BilgeAlarm KiCad files?
From the phorton1/Arduino-boat-bilgeAlarm repository on GitHub, at the commit this page was made from: the board is docs/kiCad/board/bilgeAlarm.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the BilgeAlarm design in my own project?
Its repository states no licence, so its author keeps all rights: ask phorton1 before reusing the design.
