Questions
How big is the Display PCB?
It measures 71.1 × 45.7 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Display use?
19 parts, built around the LTS-6960HR. 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 Display KiCad files?
From the okemessi/midimalletg repository on GitHub, at the commit this page was made from: the board is Circuit/Display/Display.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Display design in my own project?
Its repository publishes it under the GPL-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).
