Questions

How big is the OpenController PCB?

It measures 50 × 72 mm and has 4 copper layers, 1.6 mm thick.

What parts does the OpenController use?

54 parts, built around the ESP32-WROOM-32D, TCA4311AD and WS2812B. 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 OpenController KiCad files?

From the eightonegulf/OpenController repository on GitHub, at the commit this page was made from: the board is Hardware/Main/Main.kicad_pcb and its schematic Hardware/GamecontrollerPeripheral/GamecontrollerPeripheral.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the OpenController design in my own project?

Its repository states no licence, so its author keeps all rights: ask eightonegulf before reusing the design.
