This remote is no longer in active development. It can still be ordered fully assembled from PCBWay, and the files stay here for DIY builds. The successor is homeThing C6, a universal remote with a scroll wheel, no screen, and better battery life.

Questions
How big is the Tdisplay s3 PCB?
It measures 34 × 109.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Tdisplay s3 use?
14 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 Tdisplay s3 KiCad files?
From the landonr/homeThing repository on GitHub, at the commit this page was made from: the board is Case Design/tdisplay-s3/s3.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tdisplay s3 design in my own project?
Its repository publishes it under the GPL-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).
