Questions
How big is the Board 7seg PCB?
It measures 41 × 41 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Board 7seg use?
13 parts, built around the SM420561N. 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 Board 7seg KiCad files?
From the jalmx/mini-projects-electronics repository on GitHub, at the commit this page was made from: the board is board_7seg/board_7seg.kicad_pcb and its schematic big-display/schematic/7seg_jumbo/7seg_jumbo.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Board 7seg design in my own project?
Its repository publishes it under the CERN-OHL-W-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
