Questions
How big is the 4 displays PCB?
It measures 48.3 × 35.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 4 displays use?
22 parts, built around the LTC-4627JG and BC807. 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 4 displays KiCad files?
From the xtarke/msplibs repository on GitHub, at the commit this page was made from: the board is hardware/4_displays/4_displays.kicad_pcb and its schematic hardware/4_displays/4_displays.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 4 displays design in my own project?
Its repository publishes it under the AGPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
