V-USB based Electronics board for Arcade controls
Arcade is an open-source printed circuit board by daid, from the daid/ArcadeElectronics repository on GitHub, published under the GPL-2.0 licence. It is a 2-layer board of 100 × 100 mm with 176 parts on 144 nets, routed with 1,255 tracks and 177 vias.
It is built around the ATMEGA8A-AU, PCA9532D and BC817-40, with the EX6 among its other parts. Its parts include 61 connectors, 50 resistors, 17 capacitors, 10 diodes and 8 ICs. It belongs with the retro computing and games boards and the AVR (ATmega, ATtiny) boards of this library.

It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
176 parts, built around the ATMEGA8A-AU, PCA9532D, BC817-40 and EX6. 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.
From the daid/ArcadeElectronics repository on GitHub, at the commit this page was made from: the board is Electronics/Arcade.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
