Questions
How big is the SUMÔ PCB?
It measures 87.6 × 45.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SUMÔ use?
17 parts, built around the LM1117T-3.3. 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 SUMÔ KiCad files?
From the rama39/SUMOpsel repository on GitHub, at the commit this page was made from: the board is Hardware/SUMÔ.kicad_pcb and its schematic Hardware/SUMÔ.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SUMÔ design in my own project?
Its repository states no licence, so its author keeps all rights: ask rama39 before reusing the design.

Tested with B089AW01-V.0 and HSD089IFW1-A00-V1.0 on a breadboard. I'm sure it will work with other displays from old netbooks.
