Questions
How big is the 7x4x2-pcb PCB?
It measures 151 × 76 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 7x4x2-pcb use?
45 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 7x4x2-pcb KiCad files?
From the eswai/7x4x2 repository on GitHub, at the commit this page was made from: the board is 7x4x2-pcb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the 7x4x2-pcb design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
