Questions

How big is the Board1 PCB?

It measures 98 × 96 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Board1 use?

43 parts, built around the BC547. 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-fridgeController 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.
