Questions
How big is the Board1 PCB?
It measures 61 × 92.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Board1 use?
32 parts, built around the RS485, IRLZ44N and WS2812B. 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 Board1 KiCad files?
From the phorton1/Arduino-boat-airco repository on GitHub, at the commit this page was made from: the board is docs/kicad/board1/board1.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Board1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask phorton1 before reusing the design.
