Rasle is an open-source printed circuit board by tbowmo, from the tbowmo/rasle repository on GitHub. It is a 2-layer board of 65 × 56 mm with 75 parts on 76 nets, routed with 760 tracks and 105 vias.
It is built around the ATMEGA328-AU, 74AUP1G34GW and M2.5, with the WS2812 among its other parts. Its parts include 20 resistors, 18 capacitors, 13 connectors, 5 ICs and 4 diodes. It belongs with the AVR (ATmega, ATtiny) boards of this library.
This board is an extension board for an arcade cabinet build by the members of Nerdclub.dk, main reason is to be able to make propper shutdown of the arcade cabinet / rpi, and for making easy light control during startup / shutdown sequences.
Features of the board:

The 74 most common of 75 parts.
It measures 65 × 56 mm and has 2 copper layers, 1.6 mm thick.
75 parts, built around the ATMEGA328-AU, 74AUP1G34GW, M2.5 and WS2812. 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 tbowmo/rasle repository on GitHub, at the commit this page was made from: the board is rasle.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask tbowmo before reusing the design.
