Questions
How big is the Touch controller v2 PCB?
It measures 40 × 57 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Touch controller v2 use?
29 parts, built around the ESP32-S3-WROOM-1-N8, TPD1E05U06DYAR and TLV1117-33DCY. 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 Touch controller v2 KiCad files?
From the luney112/touch-controller-v2 repository on GitHub, at the commit this page was made from: the board is kicad/mainboard/mainboard.kicad_pcb and its schematic kicad/mainboard/mainboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Touch controller v2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask luney112 before reusing the design.
