Questions
How big is the Touchpoint Topboard PCB?
It measures 51 × 96 mm and has 2 copper layers, 1.67 mm thick.
What parts does the Touchpoint Topboard use?
35 parts, built around the AS78L05RTR-E1, DA2032-ALD, EC10E1220501 and FDS6680A. 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 Touchpoint Topboard KiCad files?
From the Touchpoint-Mouse/Touchpoint-PCB repository on GitHub, at the commit this page was made from: the board is Touchpoint_Topboard/Touchpoint_Topboard.kicad_pcb and its schematic EEOP_Display/EEOP_Display.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Touchpoint Topboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask Touchpoint-Mouse before reusing the design.
